A pesticide is made up of two chemicals,A and B,in the ratio 2:3 respectively. The mass of chemical A in the pesticide is 20 grams. What is the mass of chemical B in the pesticide.
Given that the ratio of chemicals A to B is 2:3, and the mass of chemical A is 20 grams, we can set up a proportion to calculate the mass of chemical B.
2/3 = 20/x
Cross multiply:
2x = 3 * 20
2x = 60
Divide by 2:
x = 30
Therefore, the mass of chemical B in the pesticide is 30 grams.
