A carpet sells for $28.99 a square yard. What is the price of the carpet per square meter?
9966 [12]

It is given that the price of the carpet is $ 28.99 per square yard

Step 1: Convert square yard to square meter

1 square yard = 0.836 square meter

Step 2: Calculate the cost/square meter

Now based on the relation in step (1) we can write

0.836 square meter of carpet costs $ 28.99

Therefore the cost of 1 square meter of the carpet would be

= $ 28.99 * 1 sq meter/0.836 sq meter

= $ 34.68

Answer:

1 g of Carbon

Explanation:

This is because because carbon has lower molar mass than thorium or copper so a 1-g sample of carbon contains more atoms than 1 g of cobalt or lead.

A student measures the mass of an 8 cm block of brown sugar to be 12.9 g. What is the density of
horrorfan [7]

Answer:

0.0025g/cm³

Explanation:

Given parameters:

Mass of the brown sugar = 12.9g

dimension of the sugar = 8cm

unknown:

density of the sugar = ?

Solution

Density is defined as the mass per unit volume of a substance. The expression is given below:

      Density = \frac{mass}{volume}

We know the mass of the substance but the volume is unknown:

Volume of the brown sugar = l x bx h = 8x8x8 = 512cm³

Density of the brown sugar = \frac{12.9}{512} = 0.0025g/cm³

The volume of a gas is 1.15 L at STP. At what temperature would the volume of the gas increase to 1.56 L, if the pressure is dec
denis23 [38]

A gas occupies 1.15 L at standard pressure and temperature and 1.56 L at 317 K and 650 mmHg, assuming ideal behavior.

<h3>What is an ideal gas?</h3>

An ideal gas is a gas whose behavior can be explained through ideal gas laws. One of them is the combined gas law.

A gas occupies 1.15 L (V₁) at STP (T₁ = 273,15 K and P₁ = 760 mmHg). We can calculate the temperature (T₂) at which V₂ = 1.56 L and P₂ = 650 mmHg, using the combined gas law.

\frac{P_1 \times V_1}{T_1} = \frac{P_2 \times V_2}{T_2}\\T_2 = \frac{P_2 \times V_2 \times T_1}{P_1 \times V_1} = \frac{650mmHg \times 1.56 L \times 273.15K}{760mmHg \times 1.15 L} = 317 K

A gas occupies 1.15 L at standard pressure and temperature and 1.56 L at 317 K and 650 mmHg, assuming ideal behavior.
