Many angiosperm species rely on the interaction between animals and their flowers for reproduction. As insects, birds or other animals move from one flower to another feeding on nectar, they commonly distribute pollen from flower to flower as they go which leads to plants being pollinated and seeds to be produced.

<u>Answer:</u> The mass of 1 mole of lithium is 6.941 grams.
<u>Explanation:</u>
To calculate the mass of a compound or element, we use the formula used to calculate the number of moles:
Where,
Number of moles of lithium = 1 mole
Given mass of lithium = ? g
Molar mass of lithium = 6.941 g/mol
Putting value in above equation, we get:
Hence, the mass of 1 mole of lithium is 6.941 grams.
isotopes have the same atomic number because they are the same element but have a different atomic mass because they contain a different number of neutrons.
