Given that,

Volume, d = 2 mL

Mass, m = 18 grams

We have to find the density. Density of an object is equal to mass per unit volume. It can be given by:

d=\dfrac{m}{V}\\\\d=\dfrac{18\ g}{2\ cm^2}\\\\d=9\ g/cm^3

So, the density is 9 g/cm³.

Sixty liters of a gas were collected over water when the barometer read 663 mmhg , and the temperature was 20∘c. what volume wou
lesya [120]
First, let's compute the number of moles in the system assuming ideal gas behavior. 

PV = nRT
(663 mmHg)(1atm/760 mmHg)(60 L) = n(0.0821 L-atm/mol-K)(20+273 K)
Solving for n,
n = 2.176 moles

At standard conditions, the standard molar volume is 22.4 L/mol. Thus,

Standard volume = 22.4 L/mol * 2.176 mol =<em> 48.74 L</em>

Nostrana [21]

Explanation:

an increase in concentration increases the rate of the reaction. This is because there are more reactant particles available which allows for more effective collisions between reactant particles in a given period of time. More effective collisions bring about a faster rate of reaction.
