I'm having a very difficult time with my chemistry homework! These are the questions:
What mass of water would be needed to produce a 13% iron chloride solution that contains 19g of the solute?
What mass of sodium chloride will dissolve in 100g of water at 50% Celsius

Thanks!

(19 g) / (0.13) = 146 g total
(146 g total) - (19 g solute) = 127 g water

36.69 g NaCl in 100 g H2O at 50 °C says the source below.
