Answer:
120g Using Density Equation.
Explanation:
Density =mass/volume
We need to the solve for the mass.
Mass=Density * Volume
Mass= 2.40 g/ml * 50.0 ml = 120g
I believe it is 65.37.
Let me know if this is correct. Also good luck!!
Answer:
your answer is 12 hope it's correct answer

Answer:
Q.1
Given-
Volume of solution-1 L
Molarity of solution -6M
to find gms of AgNO3-?
Molarity = number of moles of solute/volume of solution in litre
number of moles of solute = 6×1= 6moles
one moles of AgNO3 weighs 169.87 g
so mass of 6 moles of AgNO3 = 169.87×6=1019.22
so you need 1019.22 g of AgNO3 to make 1.0 L of a 6.0 M solution
