Question

How many GRAMS are in 15.73 mol of Pb(NO3)2?

A. 350 g/mol
B. 3506 g/mol
C. 3501 g/mol
D. 3507 g/mol

Answer 1

To find the number of grams in 15.73 mol of Pb(NO3)2, calculate the molar mass of Pb(NO3)2 and convert from moles to grams.

Step-by-step explanation:

To calculate the number of grams in 15.73 mol of Pb(NO3)2, we need to use the molar mass of Pb(NO3)2. The molar mass of Pb(NO3)2 is the sum of the molar masses of Pb, N, and O, multiplied by the number of atoms of each element in the compound.

The molar mass of Pb(NO3)2 = (1 × atomic mass of Pb) + (2 × atomic mass of N) + (6 × atomic mass of O)

Once you find the molar mass of Pb(NO3)2, you can convert from moles to grams using the formula:

Grams = Moles × Molar mass
