If 25cm3 of a quantity of wood ash has a mass of 45g,calculate the density of wood ash in kgm-3

.045 kg / (25 *10^-6 m^3) = 1800 kg/m^3

1.8 times density of water ? Are you sure data is correct?

25 cm^3 of water has mass of 25 grams

To calculate the density of wood ash in kg/m^3, you need to divide the mass by the volume.

Step 1: Convert cm^3 to m^3
1 cm^3 = 1 x 10^-6 m^3 (because 1 m = 100 cm)

So, 25 cm^3 = 25 x 10^-6 m^3

Step 2: Convert g to kg
1 g = 0.001 kg (because there are 1000 grams in 1 kilogram)

So, 45 g = 45 x 0.001 kg

Step 3: Calculate the density
Density = mass/volume

Density = (45 x 0.001 kg) / (25 x 10^-6 m^3)

Density = 1800 kg/m^3

Therefore, the density of wood ash is 1800 kg/m^3.

To calculate the density of wood ash, we need to use the formula:

Density = Mass / Volume

Given that the mass of the wood ash is 45g and the volume is 25cm³, we can proceed with the calculation:

1. Convert the volume from cm³ to m³:
- 1 cm³ = (1/100)^3 m³ (since there are 100 cm in 1 m)
- 1 cm³ = 1/1,000,000 m³
- Therefore, the volume in m³ is 25/1,000,000 m³ = 0.000025 m³

2. Convert the mass from grams to kilograms:
- 1 g = 1/1000 kg (since there are 1000 g in 1 kg)
- Therefore, the mass in kg is 45/1000 kg = 0.045 kg

3. Substitute the values into the formula for density:
- Density = 0.045 kg / 0.000025 m³
- Density = 1800 kg/m³

Therefore, the density of wood ash is 1800 kg/m³.
