Answer:

The oxygen molecules will spread out evenly and many will enter the cell by passing through tiny openings in the membrane.

Explanation:

A cell membrane will allow the oxygen to enter by diffusion. Diffusion is the movement of particles from an are of higher concentration to an area of lower concentration. Water, carbon dioxide, and oxygen are among the few simple molecules that can cross the cell membrane by diffusion.

How many moles are in 83.1g of CaBr2

9966 [12]

Answer:

0.416 mol CaBr₂

General Formulas and Concepts:

Chemistry - Atomic Structure

Reading a Periodic Table
Using Dimensional Analysis

Explanation:

Step 1: Define

83.1 g CaBr₂

Step 2: Identify Conversions

Molar Mass of Ca - 40.08 g/mol

Molar mass of Br - 79.90 g/mol

Molar Mass of CaBr₂ - 40.08 + 2(79.90) = 199.88 g/mol

Step 3: Convert

$83.1 \ g \ CaBr_2(\frac{1 \ mol \ CaBr_2}{199.88 \ g \ CaBr_2} )$ = 0.415749 mol CaBr₂

Step 4: Check

We are given 3 sig figs. Follow sig fig rules and round.

0.415749 mol CaBr₂ ≈ 0.416 mol CaBr₂
