Can you solve this problem Olive oil has a density of 0.91 gmL Assume that it is made up entirely of triglycerides with the molar molecular mass you estimated above What is the molarity of trig?
Luciaestebangago
No, this cannot be answered. This is explained below:
Please remember that
- density is in g / mL (gram per millilitre)
- and molar mass is in g / mol (grams per mole)
- and molarity is in mol / mL (moles per millilitre)
Without molar mass (in g/mol) molarity cannot be calculated from just knowing it is an triglyceride with density 0.91 g/mL (which is of no significance for this question, many trig's have a comparable density).

How do you fnd the molarity?
Molarity = Grams/(Molecular Weight X Volume)
Find the molarity?
Molarity = Grams/(Molecular Weight X Volume)
What is the difference between treaty v executive agreement?
molarity x molecular weight x volume=gram molarity= gram/molecular weight x volume abdulrazzaq
Do you need to know atomic weight to calculate molarity?
Yes, you definitely need to know the molecular weight of a compound to calculate molarity.
Definition of molarity and its equation?
molarity is the number of moles dissolved per volume of a solution in dm cube molarity=mass of solute in gram __________________ 1 * _________________ molecular mass of solute volume of solution in dm cube OR molarity=no.of moles ________________ volume of solution in dm cube
What is the molecular mass of 13g of NaCl?
The molecular mass of sodium chloride is 58,44 g; 13 g is equal to 0,222 moles.
How do you find mass of a solute when cubic centimeters and molarity is given?
You know the molarity and you know the volume. First off you find the moles. Molarity divided by 1000, multiplied by the volume in cm^3. Then you multiply the moles by the molecular mass of the solute, to get the weight in grams.
How do I convert molar concentration to grams?
grams divided by the molecular weight to get to moles moles divided by volume to get molarity
Does a protein solution have a high molarity?
No. The reason is that low molecular weight compounds tend to have high molarity. As an example NaF is 42.5 molecular weight. So 42.5g dissolved in 1 liter of water would only be 4.25% but be 1 molar. Proteins tend to have every high molecular weight. So if a protein was say 1000 molecular weight, a 10% solution would contain 100g but only be 0.1 molar.
What will be the molarity for a solution prepared by dissolving a 10 grams compound with a molecular mass of 100 in 1 L of water?
Molarity = moles of solute/Liters of solution 10 grams of compound ( 1mol/100g ) = 0.1 mole Molarity = 0.1 mol/1 Liter = 0.1
What information is necessary to determine the molarity of a solution if the chemical formula of the solute is known?
You know the chemical formula. You can get the molecular weight from this. You need the end volume and you also need the mass of solute.
If 154 grams of glucose are dissolved to yield one liter of solution what is the molarity of the solution?
Molarity = moles of solute/Liters of solution Find moles glucose, which is molecular formula------C6H12O6 154 grams C6H12O6 (1 mole C6H12O6/180.156 grams) = 0.8548 moles C6H12O6 Molarity = 0.8548 moles C6H12O6/1 Liter = 0.855 M glucose ---------------------------
