QuestionCalculate the percentage of lead in a bullet with 9.1 g lead, 0.2 g tin, and 1.0 g antimony. Round to the nearest whole percent.

Studdy Solution

STEP 1

Assumptions1. The bullet contains9.1g of lead. The bullet contains0.g of tin3. The bullet contains1.0g of antimony4. We are asked to find the percentage of lead in the bullet

STEP 2

First, we need to find the total weight of the bullet. We can do this by adding up the weights of the three metals.
Total weight=Weight of lead+Weight of tin+Weight of antimonyTotal\, weight = Weight\, of\, lead + Weight\, of\, tin + Weight\, of\, antimony

STEP 3

Now, plug in the given values for the weights of the lead, tin, and antimony to calculate the total weight.
Total weight=9.1g+0.2g+1.0gTotal\, weight =9.1g +0.2g +1.0g

STEP 4

Calculate the total weight of the bullet.
Total weight=9.1g+0.2g+1.0g=10.3gTotal\, weight =9.1g +0.2g +1.0g =10.3g

STEP 5

Now that we have the total weight of the bullet, we can find the percentage of lead in the bullet. This can be done by dividing the weight of the lead by the total weight and then multiplying by100 to convert the decimal to a percentage.
Percentage of lead=(Weight of lead/Total weight)times100Percentage\, of\, lead = (Weight\, of\, lead / Total\, weight) \\times100

STEP 6

Plug in the values for the weight of the lead and the total weight to calculate the percentage of lead.
Percentage of lead=(9.1g/10.3g)times100Percentage\, of\, lead = (9.1g /10.3g) \\times100

STEP 7

Calculate the percentage of lead in the bullet.
Percentage of lead=(9.1g/10.3g)times100=88.3%Percentage\, of\, lead = (9.1g /10.3g) \\times100 =88.3\%The percentage of lead in the bullet is88.3%.
