Bubbling if you put it in a liquid
Answer:
2.64gram
Explanation:
Molarity, which refers to the molar concentration, is calculated thus:
Molarity = number of moles (n) ÷ volume (L)
According to the question, volume = 100 mL, molarity = 0.240 M.
Since 1L = 1000mL
100 mL = 100/1000
= 0.1L
Hence;
0.240 = n/0.1
n = 0.1 × 0.240
n = 0.024mol
Mole = mass/molar mass
Molar mass of CaCl2 = 40 + 35.5(2)
= 40 + 71
= 111g/mol
mass = molar mass × mole
mass = 110 × 0.024
Mass = 2.64gram
When atoms share six electrons, they are joined by a double bond. (.5 points)
a. True
b. False?
Is False
Answer:
= 100u. Hence 10 g = 0.1 mole. Hope it's helpful to u
