Answer:
1656.12grams
Step-by-step explanation:
To calculate the mass of a substance in a particle, we need to calculate the number of moles (n).
n = nA × 6.02 × 10^23
nA = 8.98 x 10^24 particles
number of moles = 8.98 x 10^24 ÷ 6.02 × 10^23
n = 8.98/6.02 × 10^ (24 - 23)
n = 1.492 × 10^1
n = 14.92moles of CaCl2
Molar Mass of CaCl2 where Ca = 40g/mol, Cl = 35.5g/mol
CaCl2 = 40 + 35.5(2)
= 40 + 71
= 111g/mol
Using mole = mass/molar mass
mass = molar mass × mole
mass = 111 × 14.92
mass = 1656.12grams.
