ci=oncentration of pottasium = 3.5 * 10^-2 mol/litre
Answer:
121.63 g/mol
Explanation:
Sr(OH) 2 = Strontium Hydroxide
Number of moles = 0.51 mol
Given data:
Mass of CO₂ = 22.4 g
Number of moles = ?
Solution:
Number of moles of CO₂:
Number of moles = mass/molar mass
Molar mass of CO₂ = 44 g/mol
by putting values,
Number of moles = 22.4 g/ 44 g/mol
Answer: D
