Answer:-
190.23 gram mol-1
Explanation:-
Molar mass is the mass of 1 mole of that substance. It's unit is gram / mol or gram mol-1.
For an element it is equal to it's atomic weight.
The atomic weight of Osmium is 190.23
Hence the molar mass of Osmium is 190.23 gram / mol
Answer:
it can be done using the method of lithium paper
A straight-chain alkane differs from a cycloalkane in such a way that the straight-chain has more hydrogen than the cycloalkane. In this case, straight-chain has two more Hydrogen atoms than the cyclic alkane. Basically, they differ in the number of hydrogen atoms attached to the carbon. Straight-chain Alkane has a formula CnH2n+2 while cyclic alkane follows CnH2n.
Answer:
the answer would be C of not C is B
Answer:

Explanation:
Hello,
In this case, by knowing that the pOH is defined in terms of the concentration of OH⁻ as shown below:
![pOH=-log([OH^-])](https://tex.z-dn.net/?f=pOH%3D-log%28%5BOH%5E-%5D%29)
We directly compute with the given concentration:

Moreover, fur such pOH, the pH will be:

Which means that such solution is an acid solution.
Best regards.
