This is a stupid question. May I ask, 4.5g (or 2.6g) of what? I presume "g" means grams. If it were water, then the volume would be 4.5 cubic centimetres (cc). Any other liquid or solid (forget gasses) would be a fraction, or multiple of its specific gravity. Actually, I am sick of this. Please wipe my name from your records,
The density of the object is 9 g/cm^3 (45 g / 5 cm^3). Density is a measure of how much mass is contained in a given volume, so it describes how compact the molecules are within the object. With this information, you can calculate the mass or volume of the object given the other value.
To find the volume of the acetylene gas at STP, we can use the ideal gas law equation: PV = nRT. First, we must convert the given mass of acetylene gas to moles using its molar mass. Then, knowing STP conditions (standard temperature = 273 K and standard pressure = 1 atm), we can calculate the volume.
1 mole of sodium oxide contains the fewest sodium atoms because it contains 1 mole of sodium atoms. Each of the other compounds (45g of sodium fluoride, 50g of sodium chloride, and 1 mole of sodium nitrate) contains more than 1 mole of sodium atoms.
750ml is a measure of volume. It stands for milliliters, which is used to measure capacity or volume of liquids.
That would depend directly on the picture given to you on the assignment.
200g
The object's density is about 0.19 g/cm3
The rock's density is 3 g/cm3
The volume of 45g of face cream can vary depending on its density. However, a rough estimation would be approximately 45mL, as 1g of most creams is roughly equivalent to 1mL in volume. It is best to check the packaging for specific information on the product.
45g = 0.045kg
No, 45g is not equal to 50mL. Grams and milliliters are different units of measurement. Grams measure mass or weight, while milliliters measure volume. To determine if 45g is equal to 50mL, you would need to know the density of the substance being measured.
The increase in mass is 45g (245g - 200g) due to the added liquid. This corresponds to a volume of 26ml because 1g/ml is the density of water (and marketed) liquids. Therefore, the density of the liquid is 45g / 26ml = 1.73 g/ml.
Density = Mass/Volume D = M/V D = 45g/15ml D = 3g/ml
A 30ml solution with a mass of 45g has a density of 45/30 or 1.5 g/ml, while a 40ml solution with a mass of 50g has a density of 50/40, or 1.25 g/ml. The 30ml solution with a mass of 45g has a higher density.
45.
45g
Density = Mass / Volume Density = 45grams/5ml = 9g/ml
