HELP ME PLEASE I NEED IT LIKE RN, (WILL OFFER BRAINLIEST) A mixture of helium (He) and methane (CH4) is placed in an effusion apparatus.

V1/V2 = √m2/√m1

1. What is the molar mass of He? (round to the nearest hundredths)

2. What is the molar mass of CH4 (round to the nearest hundredths)

3. What is the ratio of the effusion rate of the helium to methane (Round to hundredths)

Ase your answer to this question on the information below.hydrocarbons and fissionable nuclei are among the sources used for the production of energy in the united states. a chemical reaction produces much less energy than a nuclear reaction per mole of reactant.the balanced chemical equation below represents the reaction of one molecule of a hydrocarbon with two molecules of oxygen.chemical equation: ch4 + 2o2 → co2 + 2h2o + 1.48 × 10−18 jthe nuclear equation below represents one of the many possible reactions for one fissionable nucleus. in this equation, x represents a missing product.nuclear equation: write an isotopic notation for the missing product represented by x in the nuclear equation.

This flow chart shows the amount of energy that is emitted by each type of light. ultraviolet > blue light > yellow light > red light (maximum energy) (minimum energy) in an experiment, shining which type of light on a strip of metal would be least likely to produce the photoelectric effect? ultraviolet light dim blue light bright red light bright yellow light

Can someone me with 3 and 4 plz. this is for masteries test.
