Answer:
CO2 molecule is made up of Carbon (atomic mass =12) and oxygen (atomic mass=16).
So first finding the mass of 1 molecule of CO2 which is equals to
= mass of 1 carbon atom + masses of 2 oxygen atom, we get
= 12+(16*2)= 12+32= 44 a.m.u.
Now 1 molecule of CO2 has mass 44 amu so mass of 1 mole CO2 will be 44 grams.( 1 a.m.u.=1.6729*10^-33 grams. 1 mole = 6.022*10^23, so 44 a.m.u.=73.6076*10^-33 grams approx. For one mole CO2, 73.6076*10^-33*6.022*10^23 which is approximately equals to 44 grams. )
1 mole CO2= 44grams, so 2.5 moles = 44*2.5= 110 grams
So our answer is 110 grams
Answer:
DMs are not accessible anymore. I assume Zuka is a staff member? the only way to talk to a staff member anymore is to report something, but even then, the probably won't even look at what they're deleting :/
May I have brainliest please? :)
The answer is B because that that will make it more powerful but less lasting.
Answer:
<em> It takes 186.67 second for the light to travel from Mars to earth.</em>
Explanation:
Light: Light is a visible form of energy which is radiated outward from a source. Light travels in a straight line, and this phenomenon is called rectilinear propagation of light.
S = d/t .......................... Equation 1
making t the subject of the equation
t = d/S ......................... Equation 2
Where S = speed of light, d = distance between the earth and Mars, t = time
<em>Given: d = 56000000 km, S = 300000 km per seconds.</em>
<em>Substituting these values into equation 2</em>
<em>t = 56000000/300000</em>
<em>t = 186.67 seconds.</em>
<em>Thus it takes 186.67 second for the light to travel from Mars to earth.</em>
