How many grams are in 2.50 moles of H2O?
To calculate the number of grams in 2.50 moles of H2O, you first need to know the molar mass of water (H2O), which is approximately 18.015 g/mol. Then, you can use the formula: grams = moles x molar mass. So, 2.50 moles of H2O is equivalent to 45.04 grams (2.50 moles x 18.015 g/mol).
How many grams of carbon dioxide would be produced if 45 grams of glucose completely react with oxygen?
The chemical equation for the combustion of glucose is C6H12O6 + 6O2 -> 6CO2 + 6H2O. From this, we can see that 1 mole of glucose produces 6 moles of CO2. Therefore, 45 grams of glucose (which is approximately 0.25 moles) would produce 6 times that amount of CO2, which is about 90 grams.
Calculate the number of moles of oxygen that will dissolve in 45 L of water at 20C if the partial pressure of oxygen is 0.21 ATM Henrys constant for oxygen is 0.0013 mol L ATM?
Using Henry's law, the number of moles of oxygen that will dissolve is calculated by multiplying Henry's constant by the partial pressure of oxygen and the volume of water. So, moles of oxygen = 0.0013 mol L ATM * 0.21 ATM * 45 L = 0.1233 mol of oxygen will dissolve in 45 L of water at 20C.
How many grams of carbon dioxide would be produced if 45 g of C6H12O6 completely reacted with oxygen?
The balanced chemical equation for the combustion of glucose (C6H12O6) is: C6H12O6 + 6O2 -> 6CO2 + 6H2O. From the equation, we can see that 1 mol of C6H12O6 produces 6 mol of CO2. First, calculate the number of moles of C6H12O6 in 45 g. Then use the mole ratio to find the moles of CO2 produced, and finally convert that to grams.

How many moles of water are contained in one mole of this hydrate in alum containing 45 percent water?
The moles number of water 12; the chemical formula is KAl(SO4)2.12H2O.
How many mg is 45 meq of sodium?
To convert milliequivalents (mEq) of sodium to milligrams (mg), you need to know the atomic weight of sodium. The atomic weight of sodium is approximately 23 g/mol. So, to convert 45 mEq of sodium to mg, you would multiply 45 mEq by the atomic weight (23 g/mol) to get 1035 mg.
How many moles of insulin are need to make up 45 ml of 0.0052m insulin solution?
To calculate the number of moles of insulin needed, you can use the formula: moles = Molarity × Volume (in liters). In this case, 0.0052 mol/L × 0.045 L = 0.000234 moles of insulin are required to make up a 45 ml solution.
How many moles of gas does a steel cylinder witha volume of 45 liters contain at standard temp pressure?
stp= 22.4 dm3, 1L = 1 dm3 1mole ---> 22.4dm3 xmole ---> 45dm3 45/22.4 = 2.001 moles
How many moles are in 45g of F?
The molecular mass of fluorine gas, F2 is 2(19.0) = 38.0Amount of F2 = mass of sample/molar mass = 9.5/38.0 = 0.25mol There are 0.25 moles of fluorine in a 9.5g pure sample.
How many molecules are in 45 g of silver?
To determine the number of molecules in 45 g of silver, you first need to calculate the number of moles of silver using its molar mass (107.87 g/mol). Then, you can use Avogadro's number (6.022 x 10^23) to convert moles to molecules.
