Average atomic mass of bromine atoms is 80 u. 33. The average atomic mass of a sample of an element X is 16.2 u. What are the percentages of isotopes ${}_{8}^{16}X$ ${}_{8}^{18}X$ and in the sample? Ans:Average atomic mass of sample is given as $\dfrac{16X+18\times \...
(2 x gram atomic mass of na + 1 x gram atomic mass of sulphur + 3 x- gram atomic mass of oxygen) = 10(2x23g+1 x 32g + 3 x16g) = 10 (46 g + 32 g + 48 g) = 10 x 126 g = 1260 g practise questions on atoms and molecules q1. a mole is quite often known as a ...

(c ) What is the gram atomic mass of S? Two closed vessels A and B of equal volume of $8.21L$ are connected by a narrow tube of negligible volume with an open valve. The left hand side container is found to contain $3\\ mole\\ C{O_2}$ and $2\\ mole\\ of\\ He$ at ...
Cite two reasons.Answer: The atomic weights of the elements ordinarily are not integers because: (1) the atomic masses of the atoms normally are not integers (except for 12C), and (2) the atomic weight is taken as the weighted average of the atomic masses of an atoms naturally occurring ...
The nature, again, of extremely fast objects is that they are at the maximum density, mass, and gravitational and atomic strength. Thus we see the results of the bodies in space pulled in to the center of the path as the object is long gone. ...
