To calculate volume out of mass you'll need the density figures of both compounds:
Hexane 0.6548 g/mL
Toluene 0.8669 g/mL (20 °C)
Volume of 10.0 grams: (divide mass (g) by density (g/mL) )
Hexane 10 g / 0.6548 g/mL = 15.27 mL
Toluene 10 g / 0.8669 g/mL = 11.54 mL
So, the volume of (10 g) hexane is 32% greaterthan of the same amount of toluene
10g of chloroform has a greater volume than 10g of hexane because chloroform has a higher density than hexane. Density is a measure of mass per unit volume, so for the same mass, the substance with the higher density will occupy less volume.
The density of the object is calculated by dividing the mass (10g) by the volume (20cc). So, 10g / 20cc = 0.5 g/cc. Therefore, the density of the object is 0.5 grams per cubic centimeter.
1000g is more than 10g.
The percentage strength of the solution is 20%. This is calculated by dividing the mass of the salt (10g) by the total mass of the solution (10g salt + 50g water) and multiplying by 100.
To calculate the number of moles in 10g of iodine, you need to first determine the molar mass of iodine (I), which is 126.9 g/mol. Then, you can use the formula: moles = mass / molar mass. So, moles = 10g / 126.9 g/mol ≈ 0.079 moles of iodine.
10g of chloroform has a greater volume than 10g of hexane because chloroform has a higher density than hexane. Density is a measure of mass per unit volume, so for the same mass, the substance with the higher density will occupy less volume.
The density is calculated by dividing the mass (10g) by the volume (3cm^3). So, density = mass/volume = 10g / 3cm^3 ≈ 3.33 g/cm^3.
100mg is less than 10g. 1000mg = 1g.
10g
Density is mass/volume so 10g/15cm^3 = .667 g/cm^3
Water
Of course not...different densities, different volumes per same weight.
The density of the object is 0.2 g/cm^3. This is calculated by dividing the mass (10g) by the volume (50 cm^3).
The density of the cork can be calculated by dividing its mass (10g) by its volume (40cm³). Thus, the density of the cork is 0.25 g/cm³.
The density of the object is 5 g/cm³. Density is calculated by dividing the mass by the volume. In this case, 10g / 2cm³ = 5 g/cm³.
Density is just mass per volume (usually g/mL). Take the specified mass, and then just divide it by the specified volume. For example, if you have 10g of a liquid with volume of 5mL, its density is (10g)/(5mL) = 2g/mL.
Density = (mass) / (volume) = (44 / 106) = 0.4151g/cc (rounded)
