Calculate the number of moles for each of the following:
A. 3.15 g of HNO3
B. 19.3 g of NaCl
C. 21.25 g of NaNO3
Answer (2)
The number of moles: 3.15g of H N O 3 1 mole of H N O 3 - 63g. x moles of H N O 3 - 3.15g x = 63 g 1 m o l e ∗ 3.15 g = 63 3.15 = 0.05 m o l e
The number of moles: 19.3 g of NaCl 1 mole of NaCl- 58.44g. x moles of NaCl- 19.3g. x = 58.44 g 1 m o l e ∗ 19.3 g = 58.44 19.3 = 0.33 m o l e
The number of moles: 21.25 g of N a N O 3 1 mole of N a N O 3 - 85g. x moles of N a N O 3 - 21.25g. x = 85 g 1 m o l e ∗ 21.25 g = 85 21.25 = 0.25 m o l e
Greetings, n00nst00p :)
The number of moles for 3.15 g of HNO 3 is approximately 0.05 moles. For 19.3 g of NaCl, it is approximately 0.33 moles, and for 21.25 g of NaNO 3 it is approximately 0.25 moles.
