Answer: for question 4, the answer would most likely be movement of air, water and rock
Explanation:
Answer:
150.016 grams
Explanation:
molar mass of cH3OH=12+4+16 =32 u
mass = nu. of moles × molar mass
mass= 0.2344 × 32 =7.5008 gm÷ 0.0500 = 150.016 gm
Answer:
- The molar mass of the solute, in order to convert from moles of solute to grams of solute.
- The density of solution, to convert from volume of solution to mass of solution.
Explanation:
Hello,
In this case, since molarity is mathematically defined as the moles of solute divided by the volume of solution and the weight/weight percent as the mass of solute divided by the mass of solution, we need:
- The molar mass of the solute, in order to convert from moles of solute to grams of solute.
- The density of solution, to convert from volume of solution to mass of solution.
For instance, if a 1-M solution of HCl has a density of 1.125 g/mL, we can compute the w/w% as follows:

Whereas the first factor corresponds to the molar mass of HCl, the second one the conversion from L to mL of solution and the third one the density to express in terms of grams of solution.
Regards.
