6 AnswersMathematics1 decade agoHow would I calculate it's molarity?
A solution is 0.30m of KBr. If the solution density is of 1.09g/mol, Calculate it's molarity (M).
Please I would like to do this on my own in the future. If possible please provide a detailed explanation on how it it calculated. Thank You!
1 AnswerChemistry1 decade agoHow do I calculate a concentration in molar mass?
The solution has a concentration of 0.15M (Molarity) of CH3CO2H.
1 AnswerChemistry1 decade agoConcentration and molar fraction. I have the answer, but need to learn how to resolve it on my own. HELP!?
A solution has a molar fraction of 0.20 (H2N)2CO and 0.80 molar fraction of water. Determine it's molality concentration.
Answer: 13.9m

2 AnswersChemistry1 decade agoHow do you calculate the molar volume?
Problem: An element crystallizes with a face centered cube structure. If it's atomic radius is of 3.82 Angstrom, what is the molar volume of the cell.
1 AnswerChemistry1 decade agoIs this problem missing information or am I missing something? Am I asking myself the right question?
What element is equal to 3.82 Angstrom atomic radius?
Problem: An element crystallizes with an fcc structure. If it's atomic radius is of 3.82 Angstrom, what is the molar volume of the cell.
