How many grams are in 3.45 moles CO2

Mamont248 [21]

<h3>Hello There!!</h3>

<u> To Find:-</u>

Grams Present in 3.45 Moles of Carbon.

<u>We </u><u>Know:</u><u>-</u>

Molecular Mass of Carbon Dioxide= 44.01 grams/mol or 44 grams/mol

$\text{Moles} = \frac{\text{Mass}}{\text{Molecular mass}}$

$\implies 3.45 \text{moles} = \frac{ \text{Mass}}{44 \text{g/mol}} \\ \\ \implies \text{Mass} = {44 \text{g/mol}} \times 3.45 \text{moles} \\ \\ \implies \text{Mass} = {44 \text{g/} \cancel\text{ mol}} \times 3.45 \cancel\text{moles} \\ \\ \implies \text{Mass} = 44 \text{g} \times 3.45 \\ \\ \implies \text{Mass} = \red{151.8 \text{g}}$

$\therefore \text{Mass of 3.45 Moles of Carbon Dioxide is = \red{151.8g}}$

What can be created with differential weathering

Afina-wow [57]

rocks weather at different rates and in different ways. Rocks may be more or less susceptible to weathering because of such things as composition or induration, the hardening of a rock through processes like increased temperature of formation, pressure of formation or cementation of particles by precipitated minerals.

Ammonia, NH3, can be made by reacting nitrogen and hydrogen and the equation is N2 + 3H2 --> 2NH3 How many moles of NH3 can b

Mrrafil [7]

9 moles of H2 means you have a total of 18 moles of H2 (9*2). In NH3, the hydrogen comes in sets of 3 (hence H3 at the end) 18/3=6 therefore you need to have made 6 moles of NH3 to satisfy it, since you have enough N2 this can work so you make 6 moles of NH3

How many moles of ethane gas, C2H6(g), will occupy 15.0 L at 30 degrees Celsius and 5.0 atm?

Alenkinab [10]

Answer:

3 mol

Explanation:

Given data:

Volume of ethane = 15.0 L

Temperature = 30°C

Pressure = 5.0 atm

Number of moles of ethane = ?

Solution:

PV = nRT

P= Pressure

V = volume

n = number of moles

R = general gas constant = 0.0821 atm.L/ mol.K

T = temperature in kelvin

Now we will convert the temperature.

30+273 = 303 K

5.0 atm × 15.0 L = n×0.0821 atm.L/ mol.K × 303 K

75 atm.L = n× 24.87 atm.L/ mol

n = 75 atm.L / 24.87 atm.L/ mol

n = 3 mol
