Hey there!:
Mass = 21.09 g
Volume = 6.44 mL
Therefore;
Density = mass / Volume
Density = 21.09 / 6.44
Density = 3.274 g/mL
Answer: 169ml
Explanation
At constant temperature, PV is constant
Standard pressure is 101 kpa
150ml X 114kpa=?mlX101 kpa
?=114/101 X150 = 169 ml
A loose, icy body with a long, narrow orbit is a comet
Answer:
6
Explanation:you find neutrons by subtracting the mass number from the proton for this example lithium's number of protons is 3 and mass number 9 so 9-3=6
