<span>Avogadro's number
represents the number of units in one mole of any substance. This has the value
of 6.022 x 10^23 units / mole. This number can be used to convert the number of
atoms or molecules into number of moles. We calculate as follows:
</span>1.40x10^23 molecules of N2 ( 1 mol / 6.022 x 10^23 molecules ) ( 28.02 g / mol ) = 6.51 g N2
The magnesium dissolves to form magnesium chloride and hydrogen gas is released.
Mg + 2HCl -----> MgCl2 + H2(g).
Answer: The length of the tropical parasite insect in centimeters is 9.3 cm.
Explanation: We are given the length of the parasite insect in milimeters and we need to convert it into centimeters. So, for that we use the conversion:
1 centimeter = 10 milimeter
Converting 93 mm to centimeters, we divide the number by 10, we get:
Hence, the length of the parasite insect in centimeters is 9.3 cm
