Answer:
4.70 moles of water have mass of 84.6g
Explanation:
Given data:
Number of moles of water = 4.70 mol
Mass in gram = ?
Solution:
Formula:
Mass = number of moles × molar mass
Molar mass of water is 18 g/mol
Mass = 4.70 mol × 18 g/mol
Mass = 84.6 g
Thus, 4.70 moles of water have mass of 84.6g.

Answer:
70g
Explanation:
Rate = 35g of NaCl can dissolve in 100g of H2O
Use proportions for 200g of H2O:

Since 200 is double of 100, x needs to be double of 35.

Therefore the maximum amount of NaCl that can dissolve in 200g of water is 70g.
