Osmium is a chemical element with a density of 22.6 grams per cubic centimeter. a piece of osmium has a volume of 15.1 cubic centimeters. what is the mass of the piece of osmium to the nearest tenth of a gram?

341.3 g

Step-by-step explanation:

we know that

The density is equal to the ratio of the mass by the volume

D=m/V

Solve for the mass m

m=D*V

In this problem we have

D=22.6 g/cm³

V=15.1 cm³

substitute in the formula

m=22.6*(15.1)=341.26 g

Round to the nearest tenth of a gram

341.26 g=341.3 g

.5 lb

step-by-step explanation:

12 in / 6 in =2 in

.25 x 2 = .5 lb

answer: city needs 2.4 inches of rainfall more to match the record of 40 inches.

step-by-step explanation:

since we have given that

total annual rainfall a city record = 40 inches

this year, total rainfall recorded = 37.6 inches

number of inches of rainfall   is needed to match the record of 40 inches is given by

hence, city needs 2.4 inches of rainfall more to match the record of 40 inches.
