Answer:
1+1=2 Unless this is a trick question. Then it's most likely 11.
Explanation:
Answer is: the compound is B₂O₃.
ω(O) = 68.94% ÷ 100%.
ω(O) = 0.6894; percentage of oxygen in the compound.
ω(X) = 31.06% ÷ 100%.
ω(X) = 0.3106; percentage of unknown element in the compound.
If we take 69.7 grams of the compound:
M(compound) = 69.7 g/mol.
n(compound) = 69.7 g ÷ 69.7 g/mol.
n(compound) = 1 mol.
n(O) = (69.7 g · 0.6894) ÷ 16 g/mol.
n(O) = 3 mol.
M(compound) = n(O) · M(O) + n(X) · M(X).
n(X) = 1 mol ⇒ M(X) = 21.7 g/mol; there is no element with this molecular weight.
n(X) = 2 mol ⇒ M(X) = 10.85 g/mol; this element is boron (B).
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
