What is the density of an object with a mass of 16 g and 3.0 ml
1 answer:
Answer:
D = 5.3 g/mL
Explanation:
Density = Mass over Volume
D = m/V
Step 1: Define
D = unknown
m = 16 g
v = 3.0 mL
Step 2: Substitute and Evaluate
D = 16 g / 3.0 mL
D = 5.333333333 g/mL
Step 3: Simplify
We have 2 sig figs.
5.333333333 g/mL ≈ 5.3 g/mL

N = (PV)/RT (T = 88.78 + 273 = 361.78K) (R = 22.4/273 = 0.082) = (5.49 x 22.03)/(0.082 x 361.78) = ? Put it into the calculator. It's hard to do that on a mobile phone.
