Answer:
37.44g
Step-by-step explanation:
- An experiment requires .64mol of NaCl to be dissolved in water.
- Number of moles of NaCl = 64mol
We are given to calculate the mass of NaCl that we would use.
- Molecular Mass of NaCl is 58.44 g/mol (approximately)
The relation b/w Given mass, molecular mass and number of moles is
Here,
- (n) represents number of moles,
- (m) represents given mass and,
- (M) represents Molecular mass
Using the above relation, we have:
- m = n × M
- m = .64 × 58.44 g
- m = 37.40 g
37.44g
Therefore, we would use 37.44g of Nacl
