Search: How many grams of glucose are in 100.mL of the final solution?

Number of results: 13,194

Chemistry
The term mole is used in chemistry to define an amount of a substance. For example, a mole of glucose, blood sugar, weighs 180.16 grams. A common concentration unit for solutions is moles of substance per liter of solution. We abbreviate this with the symbol M. For example, 0....

Write and balance the equation. C6H12O6 + 6O2 ==> 6CO2 + 6H2O mols glucose = grams/molar mass = ? Using the coefficients in the balanced equation, convert mols glucose to mols O2. Now convert mols O2 to volume (L) using PV = nRT and the conditions listed.

how many grams of glucose are required to produce 50mL of 0.1 m solution?

chemistry
A solution is made by dissolving 15.5 grams of glucose (C6H12O6) in 245 grams of water. What is the freezing-point depression of the solvent if the freezing point constant is -1.86 C/m? Show all of the work needed to solve this problem.

Chemistry
A 5.00-gram sample of glucose, C6H12O6, [molar mass = 180.] is dissolved 10.0 grams of water What is the molality of the glucose solution? Calculate the boiling(BP) and freezing points(FP) of this solution to the nearest 0.1 C. The vapor pressure of pure water at 30C is 25.0...

Chemistry
moles glucose = 10g/180.16 = ?? moles CO2 = moles glucose x (6 moles CO2/1 mole glucose) = 6 x moles glucose.

You took 0.99ml of a hexokinase assay solution and added 10 ul of an unknown glucose sample. The absorbance at 340nm is 0.422 the extinction coefficient is 6.22x10^3 the molecular mass of glucose is 180.16g/mol. What is the concentration of glucose in the original sample... In...

biochemistry
I totally screwed up on the second part. 7.8 moles of ATP is correct, and you need to take into account how much ATP is lost by the oxidation of glucose, which is 40%. Depending on what textbooks you use, 1 molecule of glucose will yield 30, 34, or 36 ATP. But lets use 1 ...

So we have prepared 19.0 g glucose in 100 mL. We now have a 19/100 = 0.19 g/mL (that is, 0.19 g glucose per mL solution). We take a 20 mL sample of that and place a container. How many g glucose did we transfer? We transferred 0.19 g/mL x 20 mL = 3.8 g to the container. Now we...
