Explanation:

<u>First find the mass of 1 mole of water (Molecular mass)</u>

H_{2} O = 2H + O

= 2(1) + 32

= 34 \: grams

Hence 1 mole of water is 34 g

<u>C</u><u>o</u><u>m</u><u>p</u><u>a</u><u>r</u><u>e</u>

1 mole = 34 g

1.33 mole = x g

\frac{x}{34} = \frac{1.33}{1}

x = 1.33 \times 34

\color{blue}{\boxed{x = 45.2}} \: \: \: \: to \: 3 \: s.f.

Therefore 1.33 moles of water is 45.2 grams

If the temperature of a gas is increased from 20°C to 35°C, what is the new pressure if the original pressure was 1.2 atm? Assum
Marta_Voda [28]

Answer:

B.) 1.3 atm

Explanation:

To find the new pressure, you need to use Gay-Lussac's Law:

P₁ / T₁ = P₂ / T₂

In this equation, "P₁" and "T₁" represent the initial pressure and temperature. "P₂" and "T₂" represent the final pressure and temperature. After converting the temperatures from Celsius to Kelvin, you can plug the given values into the equation and simplify to find P₂.

P₁ = 1.2 atm                                    P₂ = ? atm

T₁ = 20 °C + 273 = 293 K              T₂ = 35 °C + 273 = 308 K

P₁ / T₁ = P₂ / T₂                                             <----- Gay-Lussac's Law

(1.2 atm) / (293 K) = P₂ / (308 K)                  <----- Insert values

0.0041 = P₂ / (308 K)                                   <----- Simplify left side

1.3 = P₂                                                         <----- Multiply both sides by 308

How much heat do you need to raise the temperature of 150 g of ice from -30°C to -15°c?
OLga [1]
To solve this question, you must use the formula: q=mc(change in temperature), where q is heat, m is mass, C is specific heat and temperature change is temperature change. The specific heat for ice is 2.1kJ/Kg x K (given). The change in temperature is 15 degrees Celsius (which you should change to kelvins so you can cancel out units), or 273 + 15 = 288K. The mass is 150 grams, which is 0.15 kg. Now, we can solve for q, heat. We will do this by substituting variables into the formula. After simplifying and cancelling out units, the answer we get is: 90.72kJ.

What kind of weather can Wyoming soon expect?
dezoksy [38]

Answer:

Average temperatures in July range from 85°F to 90°F during the day but cool off quickly after dark, dropping into the 50s and 60s (°F). Some regions of Wyoming are classified as desert, so there isn't much precipitation. Most of it falls as rain in the late spring and early summer, which is also a windy time of year.
