Question

1.The weight of sample of wood before drying was found to be 120kg. The percentage moisture content was found to be 50%, what is the weight of the sample of the wood after drying?

Answer 1

60 kg

Explanation:

From the question above, we obtain the following information;

• Wood sample before frying = 120 kg
• Moisture in the sample is 50%

We are required to determine the mass of wood after drying. This is given by:

• multiplying the % of water in the mixture to remove it so that we remain with dry wood.

= 50/100 × 120 kg

= 60 kg dry wood

Therefore, the mass of dry wood is 60 kg.
