Although uranium is found in rocks all over the world, nuclear power plants usually use a very rare type of uranium, U-235. Uranium is a non-renewable resource. ... Nuclear power plants do not pollute the air or emit greenhouse gases.
Answer:
Molarity = 1.23 M
Explanation:
Given data:
Molarity of NaCl = ?
Mass of NaCl = 89.94 g
Volume of solution = 1249 mL ( 1249/1000 = 1.249 L)
Solution:
First of all we will calculate the number of moles of NaCl.
Number of moles = mass/molar mass
Number of moles = 89.84 g/ 58.5 g/mol
Number of moles = 1.54 mol
Molarity:
Molarity = Number of moles of solute / volume of solution in L
Molarity = 1.54 mol / 1.249 L
Molarity = 1.23 M
It would be 36 because the atomic mass of carbon is 12
