Answer:
Molarity = 0.5 M
Explanation:
Given data:
Mass of NaCl = 2.7 g
Volume = 100 mL(100×10⁻³L)
Molarity of solution = ?
Solution:
Formula:
Molarity = number of moles / volume in litter
Number of moles:
Number of moles = mass/ molar mass
Number of moles = 2.7 g/ 58.5 g/mol
Number of moles = 0.05 mol
Molarity = number of moles / volume in litte
Molarity = 0.05 mol / 100×10⁻³L
Molarity = 0.5 M
Lipids I think... just thinking off the top of my head
Because if they were, they could contaminate the chemicals in the original container.
Answer:
AINO3 - 89 g/mol
Explanation:
Molar mass of a compound or molecule is obtained by summing the individual atomic masses of the elements that makes the compound.
In this question, the elements are Al, N and O
The molar mass is given as;
Molar mass = Al + N + 3 (O)
Al = 27
N = 14
O = 16
Molar mass = 27 + 14 + 3(16)
Molar mass = 89 g/mol
