Answer:
Their weight.
Explanation:
Weight is the measurement of gravity pushing you down, so with less gravity there would be less weight.
I dont know but i just went on here to look up my answers but it 2
Answer:
M = No.of moles of solute / Volume of solution in litres
HBr: H = 1 x 1 = 1 Br = 1 x 80
Molar mass : 81 g / mol
a. n = 27.7% / 100 =0.277 g / (81 g / mol) = 0.0034 mol
density = 1.24 g/ml ; D= m / v
b. 65.32 ml x 1 L / 1000 mL = 0.065 L
c. M= n / V
= 0.0034 mol / 0.065 L
M= 0.052 mol / L
The molarity of the concentrated HBr solution is 0.052 mol/L
Answer: c
Explanation:
A reaction in which two or more molecules combine together to result in the formation of a larger molecules then this type of reactions are known as addition reactions.
