How do you calculate milligrams of caffeine in 60 mL sample?
You have to know the concentration first. That will either be in grams per milliliter (or milligrams per milliliter), or it could be in moles per liter (molarity). If it's given in grams per milliliter, just multiply that number by 60 and multiply by 1000.If it's given in moles per liter, than first find how many moles in 60 mL by multiplying by 0.06, and then convert moles to grams using the molar mass of caffeine (194.19 grams per mole).See the Related Questions for how to convert moles to grams.
Which equivalence factor should you use to convert from 38.2 grams of K to moles of K?
can you help with this question
How do you convert 32 mmol in to grams?
1) Convert to moles. I assume mmol means minimole, so you divide by 1000. 2) Multiply the number of moles by the atomic or molecular weight. The molecular weight is different for different substances; you'll have to look it up or calculate it.
How many formula units in 47.63 grams?
It depends on the substance and its molar mass.In order to convert from grams to formula units, you must first convert grams to moles, then moles to formula units (grams --> moles --> formula units).1. Divide the mass (g) of the given substance by the substance's molar mass.2. Multiply the number of moles found in Step 1 (above) by Avogadro's number (6.022 x 1023).---- Mass substance ----- X 6.022 x 1023 formula unitsMolar mass substanceCONVERSION FACTOR47.63g substance x 1 mol substance ---- x ----- Avogadro's number///////////////////// molar mass (g) substance ////// 1 mol substance
How do you convert the micromole per liter into microgram per ml?
The formula is no. moles is mass over molecular mass. If you multiply micromole by molecular mass you get micrograms. Then you have to divide by 1000 to convert per litre to per millilitre.
Convert moles per liter into micro moles per liter?
1 mole = 106 micromoles
What would be useful for converting g mol to g L?

Grams per liter into moles per liter how to convert?
To convert grams per liter to moles per liter, you need to know the molar mass of the substance in grams per mole. Divide the given mass in grams per liter by the molar mass to get moles per liter. This conversion allows you to express the concentration of a substance in terms of its molecular weight, facilitating comparisons and calculations in chemistry.
How to convert grams to atoms?
To convert grams into atoms, you have to convert them into moles first. Get the molar mass and multiply it by the number of moles to get the atoms.

What is 2.5 grams per 100 milliliters in moles per Liter?
To convert grams per milliliter to moles per liter, you need to know the molar mass of the substance. Assuming the substance is water (H2O), its molar mass is 18.015 g/mol. Therefore, 2.5 grams per 100 milliliters is equivalent to approximately 138.6 mmol/L (millimoles per liter) for water.
How do you convert moles into grams per liter?
Since both of them are per liter....then all you need to do is a one step conversion of moles into grams using the molar mass...essentially you are going to multiply the mol/L by the molar mass in grams of the given substance...
How do you convert Milligrams per liter to moles per liter?
To convert milligrams per liter (mg/L) to moles per liter (mol/L), you first need to divide the mass in milligrams by the molar mass of the substance to obtain the number of moles. Then, you can use this number to express the concentration in moles per liter.
How do you convert 90 grams of NaCl to moles?
The answer is 1,54 moles.
How do you convert millimoles per liter to grams per milliliter?
First you divide by 1000 to convert to moles/litre. Then you find the molecular mass (add up atomic masses from the periodic table). Multiply moles per litre by the molecular mass and it is in grams per litre.
