How many grams are in 3.00 x 10^24 molecules of Zn(C2H3O2)2?
Answer:
Mass = 917.4 g
Explanation:
Given data:
Number of molecules = 3.00 ×10²⁴ molecules
Mass in gram = ?
Solution:
1 mole contain 6.022 × 10²³ molecules
3.00 ×10²⁴ molecules × 1 mol / 6.022 × 10²³ molecules
0.5×10¹ mol
5 mol
Mass in gram:
Mass = number of moles × molar mass
Mass = 5 mol × 183.48 g/mol
Mass = 917.4 g
Calculate the molar mass of NaNO3-
