Step 1

Hello. Since you have posted multiple questions and not specified which question needs to be solved, we will solve the first question for you. If you want any other specific question to be solved, then please resubmit only that question or specify the question number.

The percent composition of a component present in the mixture is calculated by dividing the mass of that component in the mixture (m_{c}) by the total mass of mixture (m_{t}) and, then multiplying it with 100.

Step 2

The percentage composition of sand in the given mi...
