1.596 grams is the mass of CuSO4 needed to prepare 100 ml solution of 0.1 M solution.
Explanation:
Data given:
Volume of the solution = 100 ml or 0.1 litre
molarity of the solution = 0.10 M
mass of CuS
= ?
atomic mass of CuS
= 159.6 grams/mole
The mass will calculated by using the following relations:
number of moles =
equation 1
molarity =
equation 2
putting the value of number of moles in equation 2
molarity = 
mass = molarity x atomic mass x volume
mass = 0.1 x 0.1 x 159.6
= 1.596 grams
1.596 grams will form 100ml solution 0.1 M
Answer:
27.03 grams
Explanation:
moles (n) = mass(m)/Molar mass(M)
moles = 1.59
mass = ?
N = 14, H = 1
M(NH3) = 14 + 3(1) = 17
Substitute the values into the equation:
nM = m
∴ m = 1.59 × 17 = 27.03
Solid, Liquid, Gas, and Plasma
Sorry but it depends on the gas in question and it's temperature of condensing /boiling point if this it 0° it will turn liquid
