Please answer I need this to get a good grade. (;

94.74 mol NO₂

General Formulas and Concepts:

Chemistry - Stoichiometry

Using Dimensional AnalysisSTP (Standard Conditions for Temperature and Pressure) = 22.4 L per mole at 1 atm, 273 K

Explanation:

Step 1: Define

3714 L O₂ at STP

Step 2: Identify Conversions

RxN:   7 mol O₂ = 4 mol NO₂

STP:   22.4 L = 1 mol

Step 3: Stoichiometry

= 94.7449 mol NO₂

Step 4: Check

We are given 4 sig figs. Follow sig fig rules and round.

94.7449 mol NO₂ ≈ 94.74 mol NO₂

Talc (french chalk) is the ingredient

Since there is the same amount of agn03 in both silver chloride and silver nitrate they produce the same amount of moles. therefore silver chloride produces the same amount of silver nitrate, so your answer is 15.0 moles of silver nitrate. i hope this !
