Sarah is ordering cheese pizza for a party of ten people she knows each pizza has 8 slices to figure out how many pizzas to orde
2 answers:
Answer:
The amount of slices every person will eat
Explanation:
We know each pizza has 8 slices and 10 persons will attend this party. If we consider a mean of 3 slices per person we'll need a total of 30 slices (10x3=30), now we divide these 30 slices between the 8 slices we haver per pizza in order to have the number of pizzas needed.
<em>Since we can't order 3.75 pizzas we round this number to 4, this way we will have 32 slices. (4x8=32)</em>
I hope you find this information useful and interesting! Good luck!

A gas made up of atoms escapes through a pinhole 0.225times as fast as gas. Write the chemical formula of the gas.
Answer:
Explanation:
To solve this problem, we must apply Graham's law of diffusion. This law states that "the rate of diffusion or effusion of a gas is inversely proportional to the square root of its molecular mass at constant temperature and pressure".
Mathematically;
r₁ is the rate of diffusion of gas 1
r₂ is the rate of diffusion of gas 2
m₁ is the molar mass of gas 1
m₂ is the molar mass of gas 2
let gas 2 be the given H₂;
molar mass of H₂ = 2 x 1 = 2gmol⁻¹
rate of diffusion is 0.225;
i .e r1/r2 = 0.225
0.225 = √2 / √ m₁
0.225 = 1.414 / √ m₁
√ m₁ = 6.3
m₁ = 6.3² = 39.5g/mol
The gas is likely Argon since argon has similar molecular mass
