Question

1. the water in the cup has a density of 1g/ml. mr. fauvell pours another liquid, substance b, into the cup of water. this sample of substance b has a mass of 6 grams and a volume of 5 milliliters. will substance b float on top of the water or sink to the bottom of the water? support your answer!! (no/improper reasoning = no credit!) substance b will sink to the bottom because it is more dense than water. 9. convert the volume of substance b above, 5 ml, into liters and then express in scientific notation.

Explanation:

Step1: Recall volume conversion factor

1 liter = 1000 milliliters.

Step2: Convert 5 mL to liters

$5\ mL\times\frac{1\ L}{1000\ mL}=0.005\ L$

Step3: Express in scientific notation

$0.005 = 5\times10^{- 3}$

Answer:

$5\times10^{-3}\ L$
