Answer:
Experimental investigations are the best type of scientific research to demonstrate the relationships between cause and effect because they allow the investigator to actively manipulate variables and control conditions. This change can be measured to gather evidence to back up or refute the relationship between cause and effect.
To determine the mass of the sugar molecules given, we need to convert the given value into moles by using the a constant. <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. Then, by using the molar mass of sugar, we can convert from moles to grams. Molar mass of sugar is 342.3 g/mol. We do as follows:
</span><span>2.50 × 10^25 molecules of sugar ( 1 mol / 6.022x10^23 g ) ( 342.3 g / 1 mol) = 14210.40 grams of sugar present</span>
