To calculate the molecular mass of a compound, you need to know two things. The first is the molecular formula, and the second is the atomic mass number of each of the elements that comprise it. The atomic mass number for each element is listed in atomic mass units under its symbol in...
mol-mass Conversion:The mass of a chemical compound can be measured as the amount of substance in the given quantity of the compound multiplied by the molecular mass of the compound. The mass of {eq}n \ \rm mol {/eq} of a compound having a molecular mass {eq}M {/eq} is given by...
Answer to: Calculate the mass of sodium acetate required to prepare 80 mL of a 0.15 M sodium acetate solution. By signing up, you'll get thousands...
Molecular weight is the total atomic mass of a molecule for a compound. Equivalent weight, on the other hand, is the portion of the compound's molecular weight associated with each valence electron. For a compound, equivalent weight takes the molecular weight and divides it by the net positive...
The molecular mass of glucose is 180 g/mole. How will you make a 0.25 M glucose solution? You need 180 gm of C6H12O6 to make 1M Solution, how much H2O will you need for this? b) also to make a 0.1M solution how much H2O will you need?
The molar mass of any solid, liquid, or gaseous substance is the number of grams of the substance in its molecular (molar) form that contains 6.0221367 X e^23 atoms of the substance (Avogadro's Number). This is because the mass of a substance is dependent on the molecular weight of the...
Given Mass of solute (K(2)CO(3))=2.5g Volume of solution =1000ml Density of solution =0.85g ml^(-1) Asked Molality of solution (m)=? Formulae: m=(W(B))/(M(B))xx(1000)/(W(A)) Explanation: m= molality of solution, M(B)= Molecular weight solute
