Answer:
1.4 g/cm³
Step-by-step explanation:
1. Calculate the <em>volume of the block</em>
V = lwh
<em>Data:
</em>
l = 150 cm
w = 0.20 m
h = 6.0 mm
(a) Convert all units to a <em>common base
</em>
w = 0.20 m × (100 cm/1 m)
w = 20 cm
h = 6.0 mm × (1 cm/10 mm)
h = 0.6 cm
<em>Calculation:
</em>
V = lwh
V = 150 × 20 × 0.60
V = 1800 cm³
2. Calculate the <em>density
</em>
Density = mass/volume
<em>Data:
</em>
m = 2.5 kg
<em>Calculation:
</em>
m = 2.5 kg Convert to grams
m = 2.5 kg × (1000 g/1 kg)
m = 2500 g
Density = 2500 g/1800 cm³
Density = 1.4 g/cm³
Science experiments usually include an independent variable, dependent variable, and control. ... Science experiments also include something called constants. A constant is the part that doesn't change during the experiment.
The atomic number of calcium is 20 which means it has 20 protons and as an atom (not an ion) it also has 20 electrons. These are in four energy levels (1 though 4) .
