how many grams of AgNO3 would need to be dissolved in 1 liter, 500mL, and 100mL in order to make a 1M solution? need to show work and answers are in grams....????
You have three problems here. The first one, g AgNO3 in 1 L.
M = moles/L
You now M and L, solve for moles. Then
moles = grams/molar mass. You know moles and molar mass, solve for grams. By the way, note that the 1 L is 1 L of solution (AFTER the AgNO3 is dissolved the final volume is made to exactly 1 L---as distinguished from adding the AgNO3 to 1 L of water). The othres are the same way; the only difference is the volume changes.
