Answer:
<h3>The answer is 0.67 cm³ </h3>
Explanation:
Density of a substance can be found by using the formula
<h3>
</h3>
Making volume the subject we have
<h3>
</h3>
From the question
mass of gold nugget = 13 g
Density = 19.3 g/cm³
Substitute the values into the above formula and solve for the volume
We have
<h3>
</h3>
= 0.673575
We have the final answer as
<h2>0.67 cm³</h2>
Hope this helps you
Answer:
a. 
b. 
Explanation:
Hello.
In this case, according to the balanced chemical reaction, we can write the law of rate proportions:
Thus, we proceed as follows:
a. Since the rate of oxygen production is 0.15 M/min, we can make the following setup:
b. Since the rate of oxygen production is 0.15 M/min, we can make the following setup:
Best regards!
Answer: A. inconsistent data
Indeed, using inconsistent data in a research or more to support an argument will only jeopardize its validity. A scientific argument supported by inconsistent data will be considered invalid and unreliable. That's why there are several scientific ways on data gathering.
B. The mouse is hungry , because you dont really know that only the mouse does
Density = 0.186 g/cm^3
Step 1. Calculate the <em>volume</em> of the block
V = lwh = 9.8 cm × 5.6 cm × 4.2 cm = 230 cm^3
Step 2. Calculate the <em>density
</em>
Density = mass/volume = 42.8 g/230 cm^3 = 0.186 g/cm^3
(<em>There is no metal with this low a density</em>.)
