0.998 g/cm³ is the density of water so you go
150g/ (0.998g/cm^3) and that gives your volume or ammout
and that is 150.3006ml or 150.3006cm^3

True at around 20 deg C, or room temperature.
At its maximum (at a pressure of 1 atmosphere), the density of water is 0.9999720 grams per cm3 at 4 deg C. Than means 150 grams has a volume of 150.0042001 cm3.
At its least dense it is 0.9584 grams/cm3 and the volume of 150 grams would be 156.511 cm3 approx.
54,0 grams of water is equivalent to 3 moles.
75 grams water is equal to 4,166 moles.
There are approximately 27 grams in 1.5 moles of water.
Two moles of water are produced.
16 grams of oxygen how many moles is 0,5 moles.
180 grams of water is 10 moles of water.
54,0 grams of water is equivalent to 3 moles.
75 grams water is equal to 4,166 moles.

To calculate the amount of hydrogen peroxide (H2O2) needed to make a 1.33 molal solution in 1500 ml of water, you first need to convert the volume of water to grams. Since the density of water is 1.0 g/ml, 1500 ml of water is equal to 1500 grams. Next, calculate the moles of H2O2 needed using the molality formula (molality = moles of solute / mass of solvent in kg). Then convert the moles to grams by multiplying by the molar mass of H2O2 (34.02 g/mol).
Water has a molecuar mass of 18. This means it weights 18g per a mole. The molecular formula for water is H20. Your answer for how many moles in 1000 grams of water is 55.5084351.
To find the number of moles in 27.8 grams of water, you would first calculate the molar mass of water (18.015 g/mol). Then, divide the given mass by the molar mass to get the number of moles. In this case, 27.8 grams divided by 18.015 grams/mol is approximately 1.54 moles of water.
There are approximately 27 grams in 1.5 moles of water.
Two moles of water are produced.
3.65 grams of water is equal to .203 moles of H2O. This means there is also .203 moles of H2 present, or .408 grams.
When 2.5 moles of oxygen react with hydrogen, they react in a 1:2 ratio to produce water. Therefore, 2.5 moles of oxygen will produce 5 moles of water. To convert moles to grams, you'll need to know the molar mass of water, which is approximately 18 grams/mol. So, 2.5 moles of oxygen will produce 90 grams (5 moles x 18 grams/mole) of water.
There are 1.5 moles of water molecules in a 27 gram sample of water. This is calculated by dividing the mass of the sample (27 grams) by the molar mass of water (18 grams/mol).
