Answer:
The mass in g, of 6.5 ml of NaNO₃ is 552.5
Step-by-step explanation:
First of all, think in the molar mass of sodium nitrate.
NaNO₃ = molar mass Na + molar mass N + (molar mass O).3
23g/m + 14 g/m + 16 . 3 g/m = 85 g/m
This are the mass of 1 mol of sodium nitrate. Let's make a rule of three to find out the mass in 6.5 moles.
1 mol of NaNO₃ weighs 85 g
6.5 moles weigh (6.5 m .85g)/1m = 552.5 g
