Answer:
751.8kg/m3
Explanation:
Assuming water's density is 1,000 kg/m3 and acetone's density is 791kg/m3
we use the formula
where 1/p is the density of the mixture, xi is the mass fraction and pi is the individual density of the components of the mixture.
To calculate xi we consider that acetone and water are in a 50% proportion, this means xi is 0.5 for both substances, now we can substitute in the formula:
now we obtain p.
<em>p=751.8kg/m3</em>
I hope you find this information useful! good luck!
Answer:
Hi how are you doing today Jasmine
It's B, because a negative charged Ion is an anion. And since it's 1- ,one valence electron is been added to H. So it has 2 valence electrons.
Hi there,
Your answere would be "when you draw conclusions"
This is because you talk about your hypothesis and what supports it at the end of an experiment.
Hope this helps!
A homogeneous mixture has the same uniform appearance and composition throughout. Many homogeneous mixtures are commonly referred to as solutions. A heterogeneous mixture consists of visibly different substances or phases. The three phases or states of matter are gas, liquid, and solid.
