Explanation:
1 grams Gallium to mol = 0.01434 mol
10 grams Gallium to mol = 0.14342 mol
20 grams Gallium to mol = 0.28685 mol
30 grams Gallium to mol = 0.43027 mol
40 grams Gallium to mol = 0.5737 mol
50 grams Gallium to mol = 0.71712 mol
100 grams Gallium to mol = 1.43425 mol
200 grams Gallium to mol = 2.86849 mol
I had this quiz too. The answer is carbon, hydrogen, oxygen. Hope this helps!
264 grams of Carbon dioxide (CO2) are needed to create a 40M solution in 150ml of solution.
Explanation:
Given :
molarity of the solution = 40M
Volume of the solution = 150ml or 0.15 litres after dividing it by 1000
compound is carbon dioxide
atomic mass of CO2 = 44.01 gram/mole
mass of CO2 = ?
moles of Co2 =?
the relation between grams and molarity is given by:
number of moles = equation 1
molarity is given by :
Molarity = equation 2
Putting the value of number of moles in equation 2
molarity =
mass = molarity x atomic mass x volume
mass = 40 x 0.15 x 44.01
= 264 grams
264 grams is the mass of carbon dioxide required to make a solution of 40 M in 150 ml of solution.
