Answer:
Molarity = 0.002 M
Explanation:
Given data:
Mass of calcium chloride = 0.321 g
Volume of water = 1.45 L
Molarity of solution = ?
Solution:
Molarity = number of moles / volume in litter.
We will calculate the number of moles of calcium chloride first.
Number of moles = mass/molar mass
Number of moles = 0.321 g/ 110.98 g/mol
Number of moles = 0.003 mol
Molarity:
Molarity = 0.003 mol / 1.45 L
Molarity = 0.002 M
Answer:
Mass = 23.36 g
Explanation:
Given data:
Number of particles of CO₂ = 3.20 ×10²³
Mass of CO₂ = ?
Solution:
1 mole contain 6.022×`10²³ particles,
3.20 ×10²³ particles × 1 mol / 6.022×`10²³ particles
0.531 mol
Mass of CO₂:
Mass = number of moles × molar mass
Molar mass = 44 g/mol
Mass = 0.531 mol× 44 g/mol
Mass = 23.36 g
Answer:
linear
Explanation:
Actually I consulted various sources too and that was the most sought answer,I just decided to answer you before studying it too
A or be i cant be certain which is correct but it think its one of the lm
I believe it would be compound.
