To calculate the mass of 2.25 moles of magnesium sulfide (MgS), first determine its molar mass. Magnesium (Mg) has a molar mass of approximately 24.31 g/mol, and sulfur (S) has a molar mass of about 32.07 g/mol. Therefore, the molar mass of MgS is 24.31 g/mol + 32.07 g/mol = 56.38 g/mol. Multiplying the molar mass by the number of moles gives: 2.25 moles × 56.38 g/mol = 127.78 grams.
On Earth, a mass of 225kg weighs 2,205 Newtons or 496 lbs.
Impossible to say with out knowing 225-grams of what? There must be a link between Mass (225-g) and Volume (cups). Think of it this way...one cup of feathers weighs much less than one cup of rocks.
It depends on 225 what. 225 grams, in kilograms is 0.225 kg
There are 362.085 Kilometers in 225 Miles.There are 362.085 Kilometers in 225 Miles.
A room that is 15 feet by 15 feet has an area of 225 square feet (15 x 15 = 225).
To find the number of moles, you need to first calculate the molar mass of C6H10S: Carbon has a molar mass of 12.01 g/mol, hydrogen has a molar mass of 1.01 g/mol, and sulfur has a molar mass of 32.07 g/mol. Adding these up gives a molar mass of 114.17 g/mol for C6H10S. Then, divide the given mass by the molar mass to find the number of moles: 225 g / 114.17 g/mol ≈ 1.97 moles.
the equation you need is PV=nRTP=1.783 atmV=445 mL (convert to L by multiplying by .001)n=moles(what you're looking for)R=.08206T=225 (change Celsius to Kelvin by adding 273)solve for n to get the amount of moles and then multiply the moles by the molar mass of CO2 to get the mass :)
NH4NO3's molar mass = 80.0gMolarity = moles of solute / liters of solution0.450 M = X / 0.500 LX = .225 molesNow we must convert X to grams because it is currently in moles.(.225 moles) / 1 * ( 80.0 grams ) / 1 mole =18 grams of NH4NO3
First, calculate the molar mass of LiClO4 3H2O. Then, convert 22.4 g to moles using the molar mass. Next, determine the molarity by dividing the moles of LiClO4 3H2O by the volume of solution in liters (225 mL = 0.225 L).
The mass of 225 g of ethanol would be 225 g. The information given about the density of ethanol is not relevant to finding the mass of the given amount (225 g) of ethanol.
Balanced equation first.Zn + 2HCl - ZnCl2 + H2now we find moles HCl by....Molarity = moles of solute/Liters of solution ( 225 ml = 0.225 Liters )0.200 M HCl = X moles/0.225 Liters= 0.045 moles HCl================Now, drive reaction backwards.0.045 moles HCl (1 mole Zn/2 mole HCl)(65.41 grams/1 mole Zn)= 1.47 grams zinc reacted----------------------------------
To find the mass of 225 mL of chloroform, you would multiply the volume by the density. Mass = Volume x Density Mass = 225 mL x 1.492 g/mL = 335.7 grams.
You cannot convert from newtons to kilograms because the newton is a force unit and the kilogram is a mass unit. However, near the surface of the earth, a 22.9-kg mass would weigh 225 newtons.
First, calculate the moles of KCl: 40.0 g / 74.55 g/mol = 0.536 mol. Then calculate the moles of water: 225 g / 18.015 g/mol = 12.49 mol. The total moles of solute and solvent is 0.536 + 12.49 = 13.03 mol. Finally, calculate the mole fraction of KCl: 0.536 mol / 13.03 mol = 0.041.
