Calculate the mass in grams of 8.24 x 1024 molecules of CO2

602.25 gm

Explanation:

1 mole of any gas contains 6.02 x 10²³ molecules of gas

6.02 x 10²³ molecules of CO₂ contains 1 mole of CO₂

8.24 x 10²⁴ molecules of CO₂ will contain 8.24 x 10²⁴/ 6.02 x 10²³ moles at STP

13.6877 moles

mol weight of CO₂ = 44 g

13.6877 moles of  CO₂ = 44 g  x 13.6877 g =  602.25 gm.

a graduated cylinder.

explanation:

the correct answer is b. a strong acid completely dissociates to its ions when dissolved in water. completely dissociates to and ions. a is incorrect because does not fully ionize to and ions and some remain as the compound . c and d are incorrect because, and do not fall into the category of bronsted lowry acids. a bronsted lowry acid is a proton donor and since both molecules do not have a proton to donate they are not bronsted lowry acids. likewise,   if we use the lewis acid definition, they cannot be acids. a lewis acid is an electron pair acceptor. both and have a complete octet so can not accept any electrons which disqualifies them as acids.
