What is the molar mass for Pb?
207.2A u
Another question is: What is the molar mass for Pb c2h3o22 2?
325.29A g/mol
Also, explain how you calculated the molar mass for Pb so4 2. 399.32 g/mol
How do you calculate the molar mass for lead?
The molar mass for lead is 207.2. There is only one atom, so leave it as is. The molar Mass of Sulfur is 32.07 - because there are two atoms in this number, you multiply it by 2. The molar mass for oxygen is 15.9994. There are 8 atoms so you multiply this number by 8.
What is the molar mass for an element?
The molar mass (or mass) of a chemical element (or chemical compound) is divided by the substance (mol). Add the standard atomic masses of the constituent atoms to calculate the molar mass.

What is 3h2o?
The common name for the chemical compound with the formula 3H2O is water. The H2O part is the formula for water. The 3 means that there are 3 molecules of water. So, 3H20 is just 3 molecules of water.
How do I calculate moles?
Use the molecular formula to find the molar mass; to obtain the number of moles, divide the mass of compound by the molar mass of the compound expressed in grams.
How many molecules are in 3h2o?
3H2O has 6 hydrogen atoms and 3 oxygen atoms. However, drawing out each equation is NOT PRACTICAL. The number of atoms can be counted without having to draw it out. To mathematical find the number of elements that make up 3H2O, we multiply the 2 by the coefficient 3 to find that there are 6 H's.
What is the name of PB c2h3o2 2?
Lead Acetate - Pb(C2H3O2)2
Lead Acetate is also known as lead(II) acetate is a white crystalline chemical compound with the formula Pb(C2H3O2)2.How do you find the empirical formula?
- Start with the number of grams of each element, given in the problem.
- Convert the mass of each element to moles using the molar mass from the periodic table.
- Divide each mole value by the smallest number of moles calculated.
- Round to the nearest whole number. This is the mole ratio of the elements and is.
What is lead Ethanoate?
Lead(II) acetate (Pb(CH3COO)2), also known as lead acetate, lead diacetate, plumbous acetate, sugar of lead, lead sugar, salt of Saturn, or Goulard's powder, is a white crystalline chemical compound with a sweet taste. It is made by treating lead(II) oxide with acetic acid. Like other lead compounds, it is toxic.
What is the formula mass of ch3?
But CH3 with a little bit of rounding is about 15 g/mole or 15 amu/molecule. In case you meant CH4, this molecule is about 16 g/mole or 16 amu/molecule.
What is the gram formula mass of Pb c2h3o2 2?
The molar mass of Pb(Cr2O7)2 is 639.2 g/mol.
How many moles are in Pb no3 2?

How many molecules are in a gram of a compound?
That is, the molar mass of a substance is the mass (in grams per mole) of 6.022 × 1023 atoms, molecules, or formula units of that substance.
How many moles are in 469g Cu no3 2?
How many grams CU(No3)2 in 1 mol? The answer is 1804.03961. We assume you are converting between grams CU(No3)2 and mole. You can view more details on each measurement unit: molecular weight of CU(No3)2 or mol The SI base unit for amount of substance is the mole.
What is lead used for?
Lead is still widely used for car batteries, pigments, ammunition, cable sheathing, weights for lifting, weight belts for diving, lead crystal glass, radiation protection and in some solders. It is often used to store corrosive liquids.
How do you find the formula mass?
To calculate formula mass, multiply the subscript of each element in the formula by the element's atomic weight (relative atomic mass) found on the periodic table. The unit for formula mass is either u or Da (Daltons). The amu has been replaced with u, even though it is still commonly used.
How do we find atomic mass?
To calculate the atomic mass of a single atom of an element, add up the mass of protons and neutrons. Example: Find the atomic mass of an isotope of carbon that has 7 neutrons. You can see from the periodic table that carbon has an atomic number of 6, which is its number of protons.
How do you find the molecular formula?
Divide the molar mass of the compound by the empirical formula molar mass. The result should be a whole number or very close to a whole number. Multiply all the subscripts in the empirical formula by the whole number found in step 2. The result is the molecular formula.
