Answer:

3.50 molal

Explanation:

Molality → Moles of solute / kg of solvent.

Let's convert the solvent's mass from g to kg

16.2 g . 1kg / 1000 g = 0.0162 kg

Let's determine the moles from the solute

2.61 g . 1 mol / 46 g = 0.0567 moles

Molality → 0.0567 mol / 0.0162 kg = 3.50 m

Balance the following reaction: _Na3PO4+_Ca(NO3)2-->_NaNO3+_Ca3(PO4)2
erica [24]

The balanced equation

2Na₃PO₄+3Ca(NO₃)₂⇒6NaNO₃+Ca₃(PO₄)₂

<h3>Further explanation</h3>

Given

Reaction

_Na3PO4+_Ca(NO3)2-->_NaNO3+_Ca3(PO4)2

Required

Balanced equation

Solution

Give a coefficient

aNa₃PO₄+bCa(NO₃)₂⇒cNaNO₃+Ca₃(PO₄)₂

Ca, left=b, right = 3⇒ b=3

P, left=a, right = 2⇒a=2

Na, left=3a, right=c⇒3a=c⇒3.2=c⇒c=6

The equation becomes :

2Na₃PO₄+3Ca(NO₃)₂⇒6NaNO₃+Ca₃(PO₄)₂
