What is the density of an unknown solid with a mass of 40g and a volume of 2ml?
The density of the unknown solid is 20 g/ml. This is calculated by dividing the mass (40g) by the volume (2ml).
What is the mass of 1 mole of calcium atom?
40g
If 40g of sea water contains 2g of salt how would you calculate the mass of the water and the mass of the salt?
The water is 38g and the salt 2g, so long as there is nothing else in the water
Does 40g equal 80cc?
Grams can't be converted to cc. Grams measure mass, while cc measure volume.
When 24g of magnesium metal is heated in air 40g of magnesium oxide is produced. What mass of magnesium would be needed in order to produce 10g of magnesium oxide?
6g
If someone placed some ice cubes ina a beaker in a warm room the total mass of the ice cubes was 40g what mass of water is formed when all the ice has melted?
the mass does not change only the shape
What is the density of an object with a volume of 20 cm3 and a mass of 40g?
2g per cm3
What is the density of an object with volume of 20cm3 and a mass of 40g?
The density of the object is 2 g/cm3. This is calculated by dividing the mass (40g) by the volume (20cm3).
How many sugar cubes in 40g?
A standard sugar cube typically weighs about 4 grams. Therefore, to find out how many sugar cubes are in 40 grams, you would divide 40 by 4, resulting in 10 sugar cubes.
What is the density of an unknown solid with a mass of 40g and a volume of 2ml?
The density of the unknown solid is 20 g/ml. This is calculated by dividing the mass (40g) by the volume (2ml).
How many moles of calcium are in a sample of 40g?
Since the gram atomic mass of calcium is 40.08 and calcium does not form polyatomic molecules, the number of moles in 40g of calcium is 1.0, to the justified number of significant digits.
What is the mass of 1 mole of calcium atom?
40g
If 40g of sea water contains 2g of salt how would you calculate the mass of the water and the mass of the salt?
The water is 38g and the salt 2g, so long as there is nothing else in the water
What is the mass of 40g of sugar water?
The mass of the sugar water would still be 40g. When a solute, like sugar, is dissolved in a solvent, like water, the mass of the solution remains the same as the individual components do not change their mass through dissolution.
What is the density of an object with a volume of 20cm3and a mass of 40g?
Density = 2 g/cm3
What is the mass of an anchor 40g or 40kg?
The mass of an anchor is 40 kg. 40 g would be too light for an anchor.
What mass of hydrogen is needed to react with 40g of copper oxide CuO plus H2-- Cu plus H20?
To find the mass of hydrogen needed to react with 40g of copper oxide (CuO), first calculate the molar mass of CuO. Then, use stoichiometry to determine the moles of CuO present in 40g. From the balanced chemical equation CuO + H2 -> Cu + H2O, you can determine the mole ratio between CuO and H2. Finally, use the molar mass of hydrogen to calculate the mass of hydrogen needed to react.
