What is the mass in grams of
0.625 mol Ba(NO3)2?(please show work)

Answer 1

Step-by-step explanation:

Using the formula as follows: mole = mass/molar mass

Molar mass of Ba(NO3)2

= 137 + (14 + 48)2

= 137 + 124

= 261g/mol

Mole = mass ÷ molar mass

0.625 mol = mass/261g/mol

mass = 0.625 × 261

mass = 163g
