2.77mg caffeine / 1oz12oz / 1canLethal dose: 10.0g caffeine = 10,000mg caffeine First, find how much caffeine is in one can of soda, then divide that amount by the lethal dose to find the number of cans. (2.77mg caffeine / 1oz) * (12oz / 1can) = 33.24mg caffeine / 1can. (10,000mg caffeine) * (1can / 33.24mg caffeine) = 300.84 cans. Since we can't buy parts of a can of soda, then we have to round up to 301 cans. Notice how all the values were set up as ratios and how the units cancelled.

The correct answer would be the third option. The chemical properties cycle through each period because the atoms' outermost shells having two or more electron shells cannot have more than eight electrons. This is following the octet rule.
Answer:
What are the following substances?
Explanation:
The molecular formula C₅H₁₀O₅ and The scaling factor =5
<h3>Further explanation</h3>
Given
Molar mass = 150 g/mol
The empirical formula = CH₂O
Required
The scaling factor
Solution
The empirical formula is the smallest comparison of atoms of compound forming elements.
A molecular formula is a formula that shows the number of atomic elements that make up a compound.
(empirical formula) n = molecular formula
<em>n = the scaling factor</em>
(CH₂O)ₙ=150 g/mol
(12+2+16)ₙ=150
(30)ₙ=150
n=5
The molecular formula : C₅H₁₀O₅
