Answer: 25.3
Explanation:
The question aks to convert 19 quibs, which is the amount of skvarnick that you obtained, to sleps.
Since, you are given the equivalence between sleps and quibs, you can build your own conversion factor, which is how the sciientific calculations are made:
- equivalence: 4 sleps = 3 quibs
- divide both sides by by 3 quibs: (4 sleps / 3 quibs) = (3 quibs / 3 quibs)
- simplify: 4 sleps / 3 quibs = 1 ← conversion factor
Now, you can multiply 19 quibs by the conversion factor:
- 19 quibs × 4 sleps / 3 quibs = 76 / 3 sleps ≈ 25.3 sleps. ← answer
The quibs units cancel out since they are in the numerator and denominator, leaving only sleps.
D. Simplification incorrect answer
Elements are always combined in the same proportion as mass
Answer:
number of atoms = 1.993 x 10^25 atoms
Explanation:
please check the attached photo of the complete question
To get the number of atoms we need to get first the mass of titanium by using this formula :
mass = density * volume
the volume of the cube = length^3
1 inch = 2.54 centimeters
2.78 inch = ??
length in cm = 2.54 * 2.78 = 7.0612 cm
so the volume = length^3 = 7^3 = 352.07528346 cm^3
bs substitution in mass formula:
when density = 4.5 g/cm and volume =352.07528346 Cm^
mass = 4.5 * 352.07528346 = 1584.33877557 g
the number of atoms = mass / molar mass * avogadro's number(constant)
= (1584.33877557/47.867 )* 6.02 * 10^23
= 33.0988 * (6.02*10^23) atoms
=1.993 x 10^25 atoms
