385 L is the volume of the air mattress with 0.55 moles of air inside the mattress and a temperature of 295 K.
<h3>What is an ideal gas equation?</h3>
The ideal gas law (PV = nRT) relates to the macroscopic properties of ideal gases. An ideal gas is a gas in which the particles (a) do not attract or repel one another and (b) take up no space (have no volume).
Using the gas law,
PV=nRT, where n is the moles and R is the gas constant. Then divide the given mass by the number of moles to get molar mass.
Given data:
P= 3.5 kPa
V=?
n= 0.55 moles of air
T= 295K
R= 8.314 (L kPa/mol K)
Putting value in the given equation:
V= 
V = 
V = 385.4132857 L
And whatever the significant figure is asked for, for example, 3 significant figures: the answer would be 385 litres.
Hence, 385.4132857 L is the volume of the air mattress.

Answer:
Oxidation: A process in which an atom loses an electron and therefore increases its oxidation number. ... So oxidation reactions need not involve oxygen. This redox reaction is actually the sum of two separate half-reactions (a reduction half-reaction and an oxidation half-reaction).

The primary function of chloroplast is to conduct photosynthesis, which is the process plants use to convert light energy into chemical energy that can be released to fuel the organisms' activities.
Answer:
The answer is
<h2>1, 214, 285.71 g/mL</h2>
Explanation:
The density of a substance can be found by using the formula
From the question
mass of gas = 8.5 × 10^9 g
But 1 L = 1000 mL
So 7 L = 7000 mL
volume = 7000 mL
So the density of the gas is
We have the final answer as
1, 214, 285.71 g/mL

Answer:
b) 3.000 mol S
Explanation:
using Avogadro's constant
1 mol = 6.02 × 10^23 atoms
we need to find the number of moles for 1.806 × 10^24
x = 1.806 × 10^24
putting it together we now have:
1 mol = 6.02 × 10^23 atoms
x = 1.806 × 10^24
cross multiply
6.02 × 10^23 x = 1.806 × 10^24
divide both sides by 6.02 × 10^23
x = (1.806 × 10^24) ÷ (6.02 × 10^23) = 3 mol
