What is 90 liters equal to in pounds?
A liter is a unit of volume, not a unit of mass (or weight) like the pound. To convert between mass and weight, you need to know the density of a substance. The formula that relates volume and mass is: mass = volume x density You'll probably find density in units such as kilogram / liter (or the equivalent gram/cubic centimeter); if you use this in the formula, you'll get the mass in kilograms. You can then convert that to pounds.
Is the mass of an object is different if it is measured US units and metric units?
The mass doesn't change; just the numbers.
What is Mass multiplied by volume?
Mass (M) x Volume (V) is not the formula for anything. Mass multiplied by Volume is the formula for density. Mass multiplied by velocity (speed with a direction) is the formula for momentum.
Is it true that the mass of an object is different if it is measured in US units and metric units?
No, the mass is the same. Only the numbers are different.
What is the density 150 mL of vegetable oil that has a mass of 5.8?
That would be (5.8)/150 mass units per mL or 0.0386666 mass units per mL

What is the mass of 5.55 1022 formula units of calcium chloride CaCl2?
The molar mass of CaCl2 is 110.98 g/mol. To find the mass of 5.55 x 10^22 formula units, you would multiply the molar mass by the number of formula units. This gives a mass of approximately 6.16 x 10^24 grams.
Mass of Na2SO4 that contains 3.011023 formula units?
This mass is 72,02 g.
A salt crystal has a mass of 0.16 How many formula units does it contain?
To determine the number of formula units in a salt crystal, you need to know the molar mass of the salt. Once you know the molar mass, you can use it to calculate the number of moles present in the crystal, and then convert that to the number of formula units using Avogadro's number, which is 6.022 x 10^23 formula units/mol.
How many formula units are contained in 1.34g CaO?
To calculate the number of formula units in 1.34g of CaO, we first need to find the molar mass of CaO. CaO has a molar mass of 56.08 g/mol. Next, we convert the given mass to moles using the formula: moles = mass / molar mass. Finally, we use Avogadro's number (6.022 x 10^23) to convert moles to formula units.
What is the formula to calculate density and units?
Density = Mass/Volume. Conversion between units will depend on what the two units are.
How many formula units are in 4.89 mil of sodium oxide?
To determine the number of formula units in 4.89 moles of sodium oxide, you need to first calculate the molar mass of sodium oxide (Na2O). The molar mass of Na2O is 61.98 g/mol. Next, you convert 4.89 moles to grams by multiplying by the molar mass. Finally, divide the mass by the molar mass of Na2O to find the number of formula units, which is approximately 4.34 x 10^23 formula units.
What is the mass of 3.01 x 1023 formula units of Fe2O3?
To find the mass of 3.01 x 10^23 formula units of Fe2O3, you first need to calculate the molar mass of Fe2O3. The molar mass of Fe2O3 is 159.69 g/mol. Then, you multiply the molar mass by the number of formula units given (3.01 x 10^23) to find the total mass. The mass of 3.01 x 10^23 formula units of Fe2O3 would be 4.81 x 10^25 grams.
How many formula units are in 5.6 g of H2S?
To calculate the number of formula units in 5.6 g of H2S, you first need to determine the molar mass of H2S, which is 34.08 g/mol. Then, you can use the formula: Number of formula units = (mass given / molar mass) * Avogadro's number. Plugging in the values, you get: (5.6 g / 34.08 g/mol) * 6.022 x 10^23 = 9.89 x 10^22 formula units in 5.6 g of H2S.
What is the formula mass of nitrogen monoxide in atomic mass units?
The formula mass of nitrogen monoxide (NO) is calculated by adding the atomic masses of nitrogen (N) and oxygen (O). The atomic mass of nitrogen is approximately 14 atomic mass units (amu) and the atomic mass of oxygen is approximately 16 amu. Therefore, the formula mass of NO is 14 + 16 = 30 amu.
How many formula units make up 21.2 of MgCl2?
To find out how many formula units of MgCl2 are in 21.2g, you can use the formula: (mass in grams)/(molar mass). The molar mass of MgCl2 is 95.211 g/mol. So, (21.2 g)/(95.211 g/mol) = 0.223 moles of MgCl2. Since there is 1 formula unit of MgCl2 in 1 mole, there are 0.223 formula units in 21.2g of MgCl2.
What is the formula for density of a object using mass and volume cubed?
Density = Mass/VolumeVolume is not cubed, although the units in which volume is expressedmay be cubed units.
