The brain is protected by the bones of the skull and by a covering of three thin membranes called meninges. The brain is also cushioned and protected by cerebrospinal fluid. This watery fluid is produced by special cells in the four hollow spaces in the brain, called ventricles.

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>

You weigh a 24K gold chain and find that it weighs 400 grams. Determine home many moles of gold atoms you have
makkiz [27]

Answer:

                     2.03 moles of Gold

Explanation:

                     Gold is one of the most precious metal metal used in many applications and mainly as a jewellery. In terms of purity it is categorized in Karats. 24 Karat is considered the purest Gold (i.e. 100 % Gold) while other Karats (14, 18, 22 e.t.c) are alloys with other metals and gyms.

Data Given:

                 Mass of Gold  =  400 g

                 A.Mass of Gold  =  196.97 g.mol⁻¹

Calculate Moles of Gold as,

                              Moles  =  Mass ÷ M.Mass

Putting values,

                              Moles  =  400 g ÷ 196.97 g.mol⁻¹

                              Moles  =  2.03 moles of Gold
