How small the unit of measurement is. The smaller the unit of measurement the more precise it is.
Answer:
2.8g/cm³
Explanation:
Given parameters:
Mass of cube = 42g
Volume of cube = 15cm³
Unknown:
Density of the cube = ?
Solution:
Density is defined as the mass per unit volume of a substance. It is mathematically expressed as:
Density = 
So;
Density = 
= 2.8g/cm³
Answer:
The mass of CO22 in total is 264 g.
The atomic mass for C is 12 g / mole.
The molar mass for CO22 is (12 + (2 × 16)) = 44 g / mole.
m C = (12 / 44) × 264 = 72 g
So, there are 72 g of C in 264 g of CO2
Explanation:
there's the answer have a good day.
The molecular formula for Hydrocarbon = C₄H₁₀
<h3>
Further explanation:</h3>
Given
50 ml hydrocarbon
200 ml CO₂
250 ml H₂O
Required
The molecular formula of Hydrocarbon
Solution
From Avogadro's hypothesis, at the same temperature and pressure, the ratio of gas volume will be equal to the ratio of gas moles
So moles Hydrocarbon : CO₂ : H₂O = 50 ml : 200 ml : 250 ml = 1 : 4 : 5
mol C in 1 mol CO₂=1, and for 4 moles CO₂ there are 4 moles C
mol H in 1 mol H₂O =2, and for 5 moles H₂O there are 10 moles H
So mol ratio C : H in compound = C₄H₁₀
Answer:
red blood cell → heart tissue → circulatory system
Explanation:
The levels of organization from the simplest level of organization to the most complex is cell, tissue, organ, organ, organ system, and organism. Red blood cells are cells, heart tissue is tissue in the heart and the circulatory system is an organ system that ensures blood, oxygen, and nutrients are flowing through the body.
