A teacher wants to have her class do the mystery challenge substance. She has 500 g of barium bromide to use as they mystery substance. It takes 52 g of barium bromide to saturate 50 milliliters of water. The teacher wants to have 100 g extra, so her students have enough barium bromide to some material to filter and some to use if there is a spill. The class has 32 students and they work in groups of four. Will she have enough barium bromide for her students?

Step-by-step explanation

The teacher wants 100 extra barium bromide so they will have...

500-100= 400

Let’s how many groups of 4 they have

32/4= 8

Let’s distribute the barium bromide equally.

400/8= 50

Since it takes 52 barium bromide to saturate 50 mL of water, they will not have enough.

true

explanation:

this is the formula: v = the value of investment at the end of the time period

p = the principal amount (the initial amount invested)

r = the annual interest rate

n = the annual frequency of compounding (how many times a year interest is added)

t = the number of years the money is invested
