2.258302785 x atoms of titanium are present in a sample containing 0.375 moles of Ti.
<h3>What are moles?</h3>
A mole is defined as 6.02214076 × 10^{23} of some chemical unit, be it atoms, molecules, ions, or others. The mole is a convenient unit to use because of the great number of atoms, molecules, or others in any substance.
To find the number atoms we need to multiply by 6.02214076 × 10^{23}.
0.375 moles x 6.02214076 ×
2.258302785 x
Hence, 2.258302785 x atoms of titanium are present in a sample containing 0.375 moles of Ti.

Answer:
See image attached
Explanation:
The hydroxide ion concentration can easily be calculated from the concentration of the metal hydroxide solutions given as shown in the solution attached. The pH can now be obtained from there using pH+pOH=14. The pH value is always greater than the the pOH value as shown in the solution to the problems attached.
Question (c) contains incorrect data that cannot be used to calculate the required parameters.
The conversion factor is added to the original given unit so that you can end up with the final unit. Basically, the conversion unit does not change the value because the factor is just equal to 1. You just manipulate the units by cancelling them.
Among the given choices, the fraction which is equal to 1 is 10⁻³ g/ 1 mg, because there are 1,000 mg per 1 g. In reverse, that would be 10⁻³ of a gram.
Answer:
In 12.6g of there are 0.29 moles of and molecules of
Explanation:
First you should find the molar mass of the :
Then you should write the conversion factor using the molar mass:
So, there are 0.29 moles of in 12.6g of .
Finally to find the number of molecules, you should use the Avogadro´s number:
There are moles of in 12.6g of
CO2 is a compound, hope this is okay
