A student has a 5. 00 gram sample of calcium chloride (cacl2) solid. How many moles of calcium chloride are contained in this sample?
Answers
Answer:
0.0451 moles ≅ 0.04 moles
Explanation:
We are able to calculate how many moles of calcium chloride (CaCl₂) are in 5.00 g sample, by dividing the mass into the molar mass (MM) of the compound:moles = mass/MMFirst, we calculate MM of CaCl₂ from the chemical formula, using the molar mass of the elements Ca and Cl:MM CaCl₂ = (1 x MMCa) + (2 x MMCl) = 40 g/mol + ( 2 x 35.453 g/mol) = 110.9 g/mol.
Finally, we calculate the moles from the mass and MM:moles of CaCl₂ = mass/(MM CaCl₂) = 5.00 g/(110.9 g/mol) = 0.0451 moles ≅ 0.04 moles
So your answer comes out as 0.0451 moles ≅ 0.04 moles.

Arc cd is of the circumference of a circle. What is the radian measure of the central angle? radians radians radians radians
Answers
If the arc cd is K times circumference, then the central angle is K times 2pi.
(where K is any real between 0 and 1).
How to find the central angle?
The question is incomplete, but it can be answered in a general form.
We know that for a circle of radius R, the circumference is:
C = 2*pi*R
While for an arc of central angle θ, the length of the arc is:
A = θ*R
Now, if we know that the arc is K times the circumference (Where K can be any real number between 0 and 1), then we have that:
A = θ*R = K*2*pi*R
Now we can solve that for the central angle:
θ = K*2*pi*R/R = K*2*pi
θ = K*2*pi
So, if the arc cd is K times circumference, then the central angle is K times 2pi.

Determine how many grams of co2 are produced by burning 2. 43 g of c4h10.
Answers
7.37g of CO₂ is formed by burning 2. 43 g of c4h10.
Calculating mass of CO2 produced.
The balanced reaction is given as
2C₄H₁₀ + 13O₂ ---> 8CO₂ + 10H₂O
The stoichiometry of C₄H₁₀ to CO₂tells us that
for every 2 mole of butane used up,8 moles of CO₂ are formedor simply
for every 1 mole of butane used up,4 moles of CO₂ are formedCalculating the number of moles used, we first find molar mass of butane
molar mass of butane = (12 g/mol x 4) + (1 g/mol *x10) = 58 g/mol
Number of moles = Mass / Molar mass
= 2. 43 g/ 58 g/mol= 0.041 8mol
Rem,
1 mol of butane forms 4 mol of CO₂
Therefore 0.041 8mo lof butane forms = 4 x0.041 8mol = 0.1675mol of CO₂
molar mass of CO₂ = 44 g/mol
Mass of CO₂ formed =0.1675mol X 44 g/mol = 7.37g of CO₂ is formed
