Table sugar has a molar mass of 342 grams. How many grams of table sugar are needed to make 2.00 liters of a 0.500 M solution?
jolli1 [7]

Answer:

342 grams of sugar are needed.

Step-by-step explanation:

This really should be in chemistry. Math types may not know any chemistry.

Step One

Find the number of moles needed in a solution of the givens.

<em><u>Givens</u></em>

V = 2.00 L

C = 0.500 moles / Liter

<em><u>Formula</u></em>

n = C * V

<em><u>Sub and Solve</u></em>

n = 2 * 0.5  = 1 mole

Since you need just 1 mole, the answer is 342 grams of sugar are needed to put into a solution of 2 Liters with a concentration of 0.500

The answer is to 3 decimal places so 342 is the answer.

A rental car costs $15 a day plus 25 cents for each mile driven. Which
blagie [28]

The expression that shows the cost to rent a car for 1 week and drive 200 miles is (15 × 7) + (0.25 × 200)

The problem can be modelled to a linear equation.

<h3>Linear equation</h3>

Linear equation can be represented in slope intercept form as follows:

y = mx + b

where

m = slope

b = y-intercept

Therefore,

y = total cost of the rental

x = mile driven

Hence,

y = 0.25x + 15

Therefore, the expression that shows the cost to rent a car for 1 week and drive 200 miles is as follows:

  • (15 × 7) + (0.25 × 200)

GrogVix [38]

Answer:

$18.15  

Step-by-step explanation:

We have been given that In Las Vegas, Nevada, stores charge a 4.6% state sales tax and a 3.65% county sales tax. Yuki is purchasing a handbag priced at $220 before tax.

To find sales tax paid by Yuki for her handbag purchase we will find 4.6% of $220 and 3.65% of $220 and add amount of both taxes.  

\text{Total sales tax amount}=\text{State sales tax amount}+\text{ County sales tax amount}

\text{State sales tax for handbag}=220\times\frac{4.6}{100}        

\text{State sales tax for handbag}=22\times 0.46

\text{State sales tax for handbag}=10.12

Now let us find county sales tax for handbag purchase.

\text{County sales tax for handbag}=220\times\frac{3.65}{100}

\text{County sales tax for handbag}=22\times 0.365

\text{County sales tax for handbag}=8.03

Now let us add both amount to get total tax paid by Yuki.

\text{Total sales tax}=10.12+8.03

\text{Total sales tax}=18.15

Therefore, Yuki paid $18.15 sales tax for her handbag purchase.
