Molar mass is the weight of one mol of a substance. It typically has units of grams per mol (g/mol). Every element or chemical has a particular molar mass that is determined by the weight of each element involved. Answer and Explanation: ...
Molar mass is the number of grams of a substance that equals one mole or6.02x1023molecules, also known as Avogadro's number. Molar mass can be used to convert between moles and grams, denoted byg/mol. Answer and Explanation: KMnO4

What is the weight ( in g) of Na(2) CO(3) molar mass = 106 ) present in 250 mL of Its 0.2 M solution ?
What is the molar mass of copper II sulfate? Copper(II) Sulfate: The formula for copper(II) sulfate is CuSO4. When five water molecules are physically attached to copper(II) sulfate, it is a blue crystal. Anhydrous (no attached water molecules) copper(II) sulfate is a white crystal. ...
=Mass of certain of gas(22.4L)at STPMass of same volume ofH2gas(22.4L)at STP =Mw2 ×2 View Solution For the formation of 3.65 g of hydrogen chloride gas, what volumes of hydrogen gas and chlorine gas are required at NTP conditions?
The molecular weightis commonly used as a synonym of molar mass, particularly for molecular compounds; however, the most authoritative sources define it differently (see Molecular mass). The formula weight is a synonym of molar mass that is frequently used for non-molecular compounds, such as ion...
