To calculate the atomic mass of an element, the atomic masses of their isotopes must be considered. Their abundances must also be taken into account. This is the formula used for the calculation:
avg. atomic mass= ∑ <span>(isotope × abundance).

Vanillin (used to flavour vanilla ice cream and other foods) is the substance whose aroma the human nose detects in the smallest

Rudiy27

Answer:

The cost is $0.063.

Explanation:

First, we need to express the volume of the hangar in liters. We know that 1 ft³ = 28.31 L, so using proportions:

$5.0 \times 10^{7} ft^{3} .\frac{28.31L}{1ft^{3} } =1.4 \times 10^{9} L$

The amount of vanillin required would be:

$1.4 \times 10^{9} L.\frac{2.0\times 10^{-11}g }{1L} =0.028g$

Finally, the price for such amount of vanillin is:

$0.028g.\frac{ \textdollar 112}{50g}= \textdollar 0.063$

Why do atoms tend to be bonded to other atoms?

Aleks04 [339]

Answer:

Atoms are often more stable when bonded to other atoms

Explanation:

Like for example let's say ionic bonds..... Since one atom has to lose specific electrons to be stable and the other needs the electrons from the other atom to be stable.....
